+>SMB networking provides a mechanism by which clients can access a list
+of machines in a network, a so-called "browse list". This list
+contains machines that are ready to offer file and/or print services
+to other machines within the network. Thus it does not include
+machines which aren't currently able to do server tasks. The browse
+list is heavily used by all SMB clients. Configuration of SMB
+browsing has been problematic for some Samba users, hence this
+document.</P
><P
->You should do ALL the tests, in the order shown. I have tried to
-carefully choose them so later tests only use capabilities verified in
-the earlier tests.</P
+>Browsing will NOT work if name resolution from NetBIOS names to IP
+addresses does not function correctly. Use of a WINS server is highly
+recommended to aid the resolution of NetBIOS (SMB) names to IP addresses.
+WINS allows remote segment clients to obtain NetBIOS name_type information

->If you send me an email saying "it doesn't work" and you have not

+>Samba can also act as a domain master browser for a workgroup. This
+means that it will collate lists from local browse masters into a
+wide area network server list. In order for browse clients to
+resolve the names they may find in this list, it is recommended that
+both samba and your clients use a WINS server.</P
+><P
+>Note that you should NOT set Samba to be the domain master for a
+workgroup that has the same name as an NT Domain: on each wide area
+network, you must only ever have one domain master browser per workgroup,
+regardless of whether it is NT, Samba or any other type of domain master
+that is providing this service.</P
+><P
+>[Note that nmbd can be configured as a WINS server, but it is not
+necessary to specifically use samba as your WINS server. NTAS can
+be configured as your WINS server. In a mixed NT server and
+samba environment on a Wide Area Network, it is recommended that
+you use the NT server's WINS server capabilities. In a samba-only
+environment, it is recommended that you use one and only one nmbd
+as your WINS server].</P
+><P
+>To get browsing to work you need to run nmbd as usual, but will need
+to use the "workgroup" option in smb.conf to control what workgroup
+Samba becomes a part of.</P
+><P
+>Samba also has a useful option for a Samba server to offer itself for
+browsing on another subnet. It is recommended that this option is only
+used for 'unusual' purposes: announcements over the internet, for
+example. See "remote announce" in the smb.conf man page. </P

->In all of the tests I assume you have a Samba server called BIGSERVER
-and a PC called ACLIENT both in workgroup TESTGROUP. I also assume the
-PC is running windows for workgroups with a recent copy of the
-microsoft tcp/ip stack. Alternatively, your PC may be running Windows
-95 or Windows NT (Workstation or Server).</P
+>If something doesn't work then hopefully the log.nmb file will help
+you track down the problem. Try a debug level of 2 or 3 for finding
+problems. Also note that the current browse list usually gets stored
+in text form in a file called browse.dat.</P
><P
->The procedure is similar for other types of clients.</P
+>Note that if it doesn't work for you, then you should still be able to
+type the server name as \\SERVER in filemanager then hit enter and
+filemanager should display the list of available shares.</P
><P
->I also assume you know the name of an available share in your
-smb.conf. I will assume this share is called "tmp". You can add a
-"tmp" share like by adding the following to smb.conf:</P
+>Some people find browsing fails because they don't have the global
+"guest account" set to a valid account. Remember that the IPC$
+connection that lists the shares is done as guest, and thus you must
+have a valid guest account.</P
+><P
+>Also, a lot of people are getting bitten by the problem of too many
+parameters on the command line of nmbd in inetd.conf. This trick is to
+not use spaces between the option and the parameter (eg: -d2 instead
+of -d 2), and to not use the -B and -N options. New versions of nmbd
+are now far more likely to correctly find your broadcast and network
+address, so in most cases these aren't needed.</P
+><P
+>The other big problem people have is that their broadcast address,
+netmask or IP address is wrong (specified with the "interfaces" option
+in smb.conf)</P

+>2.4. Browsing across subnets</H2
+><P
+>With the release of Samba 1.9.17(alpha1 and above) Samba has been
+updated to enable it to support the replication of browse lists
+across subnet boundaries. New code and options have been added to
+achieve this. This section describes how to set this feature up
+in different settings.</P
+><P
+>To see browse lists that span TCP/IP subnets (ie. networks separated
+by routers that don't pass broadcast traffic) you must set up at least
+one WINS server. The WINS server acts as a DNS for NetBIOS names, allowing
+NetBIOS name to IP address translation to be done by doing a direct
+query of the WINS server. This is done via a directed UDP packet on
+port 137 to the WINS server machine. The reason for a WINS server is
+that by default, all NetBIOS name to IP address translation is done
+by broadcasts from the querying machine. This means that machines
+on one subnet will not be able to resolve the names of machines on
+another subnet without using a WINS server.</P
+><P
+>Remember, for browsing across subnets to work correctly, all machines,
+be they Windows 95, Windows NT, or Samba servers must have the IP address
+of a WINS server given to them by a DHCP server, or by manual configuration
+(for Win95 and WinNT, this is in the TCP/IP Properties, under Network
+settings) for Samba this is in the smb.conf file.</P

+><P
+>Cross subnet browsing is a complicated dance, containing multiple
+moving parts. It has taken Microsoft several years to get the code
+that achieves this correct, and Samba lags behind in some areas.
+However, with the 1.9.17 release, Samba is capable of cross subnet
+browsing when configured correctly.</P

+on it, subnet 2 has 4 machines, subnet 3 has 4 machines. Assume
+for the moment that all these machines are configured to be in the
+same workgroup (for simplicities sake). Machine N1_C on subnet 1
+is configured as Domain Master Browser (ie. it will collate the
+browse lists for the workgroup). Machine N2_D is configured as

+>As all these machines are booted up, elections for master browsers
+will take place on each of the three subnets. Assume that machine
+N1_C wins on subnet 1, N2_B wins on subnet 2, and N3_D wins on
+subnet 3 - these machines are known as local master browsers for
+their particular subnet. N1_C has an advantage in winning as the
+local master browser on subnet 1 as it is set up as Domain Master
+Browser.</P
><P
->Also, if you do not have DNS server access for name resolution please check
-that the settings for your smb.conf file results in "dns proxy = no". The
-best way to check this is with "testparm smb.conf"</P
+>On each of the three networks, machines that are configured to
+offer sharing services will broadcast that they are offering
+these services. The local master browser on each subnet will
+receive these broadcasts and keep a record of the fact that
+the machine is offering a service. This list of records is
+the basis of the browse list. For this case, assume that
+all the machines are configured to offer services so all machines
+will be on the browse list.</P
+><P
+>For each network, the local master browser on that network is
+considered 'authoritative' for all the names it receives via
+local broadcast. This is because a machine seen by the local
+master browser via a local broadcast must be on the same
+network as the local master browser and thus is a 'trusted'
+and 'verifiable' resource. Machines on other networks that
+the local master browsers learn about when collating their
+browse lists have not been directly seen - these records are
+called 'non-authoritative'.</P

+>Once N2_B knows the address of the Domain master browser it

+>3.1. What are oplocks?</H2
+><P
+>When a client opens a file it can request an "oplock" or file
+lease. This is (to simplify a bit) a guarentee that no one else
+has the file open simultaneously. It allows the client to not
+send any updates on the file to the server, thus reducing a
+network file access to local access (once the file is in
+client cache). An "oplock break" is when the server sends
+a request to the client to flush all its changes back to
+the server, so the file is in a consistent state for other
+opens to succeed. If a client fails to respond to this
+asynchronous request then the file can be corrupted. Hence
+the "turn off oplocks" answer if people are having multi-user
+file access problems.</P
+><P
+>Unless the kernel is "oplock aware" (SGI IRIX and Linux are
+the only two UNIXes that are at the moment) then if a local
+UNIX process accesses the file simultaneously then Samba
+has no way of telling this is occuring, so the guarentee
+to the client is broken. This can corrupt the file. Short
+answer - it you have UNIX clients accessing the same file
+as smbd locally or via NFS and you're not running Linux or
+IRIX then turn off oplocks for that file or share.</P
+><P
+>"Share modes". These are modes of opening a file, that
+guarentee an invarient - such as DENY_WRITE - which means
+that if any other opens are requested with write access after
+this current open has succeeded then they should be denied
+with a "sharing violation" error message. Samba handles these
+internally inside smbd. UNIX clients accessing the same file
+ignore these invarients. Just proving that if you need simultaneous
+file access from a Windows and UNIX client you *must* have an
+application that is written to lock records correctly on both
+sides. Few applications are written like this, and even fewer
+are cross platform (UNIX and Windows) so in practice this isn't
+much of a problem.</P
+><P
+>"Locking". This really means "byte range locking" - such as
+lock 10 bytes at file offset 24 for write access. This is the
+area in which well written UNIX and Windows apps will cooperate.
+Windows locks (at least from NT or above) are 64-bit unsigned
+offsets. UNIX locks are either 31 bit or 63 bit and are signed
+(the top bit is used for the sign). Samba handles these by
+first ensuring that all the Windows locks don't conflict (ie.
+if other Windows clients have competing locks then just reject
+immediately) - this allows us to support 64-bit Windows locks
+on 32-bit filesystems. Secondly any locks that are valid are
+then mapped onto UNIX fcntl byte range locks. These are the
+locks that will be seen by UNIX processes. If there is a conflict
+here the lock is rejected.</P
+><P
+>Note that if a client has an oplock then it "knows" that no
+other client can have the file open so usually doesn't bother
+to send to lock request to the server - this means once again
+if you need to share files between UNIX and Windows processes
+either use IRIX or Linux, or turn off oplocks for these
+files/shares.</P

+be taken as the fast track guide to implementing browsing across subnets

+>4.1. Discussion</H2
+><P
+>Firstly, all MS Windows networking is based on SMB (Server Message
+Block) based messaging. SMB messaging is implemented using NetBIOS. Samba
+implements NetBIOS by encapsulating it over TCP/IP. MS Windows products can
+do likewise. NetBIOS based networking uses broadcast messaging to affect
+browse list management. When running NetBIOS over TCP/IP this uses UDP
+based messaging. UDP messages can be broadcast or unicast.</P
+><P
+>Normally, only unicast UDP messaging can be forwarded by routers. The
+"remote announce" parameter to smb.conf helps to project browse announcements
+to remote network segments via unicast UDP. Similarly, the "remote browse sync"
+parameter of smb.conf implements browse list collation using unicast UDP.</P
+><P
+>Secondly, in those networks where Samba is the only SMB server technology
+wherever possible nmbd should be configured on one (1) machine as the WINS
+server. This makes it easy to manage the browsing environment. If each network
+segment is configured with it's own Samba WINS server, then the only way to
+get cross segment browsing to work is by using the "remote announce" and
+the "remote browse sync" parameters to your smb.conf file.</P
+><P
+>If only one WINS server is used then the use of the "remote announce" and the
+"remote browse sync" parameters should NOT be necessary.</P
+><P
+>Samba WINS does not support MS-WINS replication. This means that when setting up
+Samba as a WINS server there must only be one nmbd configured as a WINS server
+on the network. Some sites have used multiple Samba WINS servers for redundancy
+(one server per subnet) and then used "remote browse sync" and "remote announce"
+to affect browse list collation across all segments. Note that this means
+clients will only resolve local names, and must be configured to use DNS to
+resolve names on other subnets in order to resolve the IP addresses of the
+servers they can see on other subnets. This setup is not recommended, but is
+mentioned as a practical consideration (ie: an 'if all else fails' scenario).</P
+><P
+>Lastly, take note that browse lists are a collection of unreliable broadcast
+messages that are repeated at intervals of not more than 15 minutes. This means
+that it will take time to establish a browse list and it can take up to 45
+minutes to stabilise, particularly across network segments.</P

+Samba LMB. It works ONLY if the Samba server that has this option is
+simultaneously the LMB on it's network segment.</P
+><P

+<PRE
+CLASS="PROGRAMLISTING"
+> remote browse sync = a.b.c.d</PRE

+>4.4. Use of WINS</H2
+><P
+>Use of WINS (either Samba WINS _or_ MS Windows NT Server WINS) is highly
+recommended. Every NetBIOS machine registers it's name together with a
+name_type value for each of of several types of service it has available.
+eg: It registers it's name directly as a unique (the type 0x03) name.
+It also registers it's name if it is running the lanmanager compatible
+server service (used to make shares and printers available to other users)
+by registering the server (the type 0x20) name.</P
+><P
+>All NetBIOS names are up to 15 characters in length. The name_type variable
+is added to the end of the name - thus creating a 16 character name. Any
+name that is shorter than 15 characters is padded with spaces to the 15th
+character. ie: All NetBIOS names are 16 characters long (including the
+name_type information).</P
+><P
+>WINS can store these 16 character names as they get registered. A client
+that wants to log onto the network can ask the WINS server for a list
+of all names that have registered the NetLogon service name_type. This saves
+broadcast traffic and greatly expedites logon processing. Since broadcast
+name resolution can not be used across network segments this type of
+information can only be provided via WINS _or_ via statically configured
+"lmhosts" files that must reside on all clients in the absence of WINS.</P
+><P
+>WINS also serves the purpose of forcing browse list synchronisation by all
+LMB's. LMB's must synchronise their browse list with the DMB (domain master
+browser) and WINS helps the LMB to identify it's DMB. By definition this
+will work only within a single workgroup. Note that the domain master browser
+has NOTHING to do with what is referred to as an MS Windows NT Domain. The
+later is a reference to a security environment while the DMB refers to the
+master controller for browse list information only.</P
+><P
+>Use of WINS will work correctly only if EVERY client TCP/IP protocol stack
+has been configured to use the WINS server/s. Any client that has not been
+configured to use the WINS server will continue to use only broadcast based
+name registration so that WINS may NEVER get to know about it. In any case,
+machines that have not registered with a WINS server will fail name to address
+lookup attempts by other clients and will therefore cause workstation access
+errors.</P
+><P
+>To configure Samba as a WINS server just add "wins support = yes" to the
+smb.conf file [globals] section.</P
+><P
+>To configure Samba to register with a WINS server just add
+"wins server = a.b.c.d" to your smb.conf file [globals] section.</P

+><P
+>A very common cause of browsing problems results from installing more than
+one protocol on an MS Windows machine.</P
+><P
+>Every NetBIOS machine take part in a process of electing the LMB (and DMB)
+every 15 minutes. A set of election criteria is used to determine the order
+of precidence for winning this election process. A machine running Samba or
+Windows NT will be biased so that the most suitable machine will predictably
+win and thus retain it's role.</P
+><P
+>The election process is "fought out" so to speak over every NetBIOS network
+interface. In the case of a Windows 9x machine that has both TCP/IP and IPX
+installed and has NetBIOS enabled over both protocols the election will be
+decided over both protocols. As often happens, if the Windows 9x machine is
+the only one with both protocols then the LMB may be won on the NetBIOS
+interface over the IPX protocol. Samba will then lose the LMB role as Windows
+9x will insist it knows who the LMB is. Samba will then cease to function
+as an LMB and thus browse list operation on all TCP/IP only machines will
+fail.</P

+><P
+>The unix and SMB password encryption techniques seem similar
+ on the surface. This similarity is, however, only skin deep. The unix
+ scheme typically sends clear text passwords over the network when
+ logging in. This is bad. The SMB encryption scheme never sends the
+ cleartext password over the network but it does store the 16 byte
+ hashed values on disk. This is also bad. Why? Because the 16 byte hashed
+ values are a "password equivalent". You cannot derive the user's
+ password from them, but they could potentially be used in a modified
+ client to gain access to a server. This would require considerable
+ technical knowledge on behalf of the attacker but is perfectly possible.
+ You should thus treat the smbpasswd file as though it contained the
+ cleartext passwords of all your users. Its contents must be kept
+ secret, and the file should be protected accordingly.</P
+><P
+>Ideally we would like a password scheme which neither requires
+ plain text passwords on the net or on disk. Unfortunately this
+ is not available as Samba is stuck with being compatible with
+ other SMB systems (WinNT, WfWg, Win95 etc). </P

+>Versions of Samba prior to release 2.2 had marginal capabilities to act

+Windows NT 4.0-style domain logons from Windows NT 4.0 and Windows
+2000 clients. This article outlines the steps
+necessary for configuring Samba as a PDC. It is necessary to have a
+working Samba server prior to implementing the PDC functionality. If

+>6.4. Creating Machine Trust Accounts and Joining Clients to the
+Domain</H2
+><P
+>A machine trust account is a Samba account that is used to
+authenticate a client machine (rather than a user) to the Samba
+server. In Windows terminology, this is known as a "Computer
+Account."</P
+><P
+>The password of a machine trust account acts as the shared secret for
+secure communication with the Domain Controller. This is a security
+feature to prevent an unauthorized machine with the same NetBIOS name
+from joining the domain and gaining access to domain user/group
+accounts. Windows NT and 2000 clients use machine trust accounts, but
+Windows 9x clients do not. Hence, a Windows 9x client is never a true
+member of a domain because it does not possess a machine trust
+account, and thus has no shared secret with the domain controller.</P
+><P
+>A Windows PDC stores each machine trust account in the Windows
+Registry. A Samba PDC, however, stores each machine trust account
+in two parts, as follows:
+
+<P
+></P
+><UL
+><LI
+><P
+>A Samba account, stored in the same location as user
+ LanMan and NT password hashes (currently
+ <TT

+ possesses and uses only the NT password hash.</P
+></LI
+><LI
+><P
+>A corresponding Unix account, typically stored in
+ <TT
+CLASS="FILENAME"
+>/etc/passwd</TT
+>. (Future releases will alleviate the need to
+ create <TT

+> entries.) </P

+successfully authenticate against a domain logon server (NT server and
+other systems based on NT server support this, as does at least Samba TNG now).</P

+>When an SMB client in a domain wishes to logon it broadcast requests for a

+password using whatever mechanism the Samba administrator has installed.
+It is possible (but very stupid) to create a domain where the user
+database is not shared between servers, i.e. they are effectively workgroup
+servers advertising themselves as participating in a domain. This
+demonstrates how authentication is quite different from but closely
+involved with domains.</P

+>There are a few comments to make in order to tie up some
+loose ends. There has been much debate over the issue of whether
+or not it is ok to configure Samba as a Domain Controller in security
+modes other than <TT
+CLASS="CONSTANT"
+>USER</TT
+>. The only security mode
+which will not work due to technical reasons is <TT
+CLASS="CONSTANT"
+>SHARE</TT
+>
+mode security. <TT
+CLASS="CONSTANT"
+>DOMAIN</TT
+> and <TT
+CLASS="CONSTANT"
+>SERVER</TT
+>
+mode security is really just a variation on SMB user level security.</P
+><P
+>Actually, this issue is also closely tied to the debate on whether
+or not Samba must be the domain master browser for its workgroup
+when operating as a DC. While it may technically be possible
+to configure a server as such (after all, browsing and domain logons
+are two distinctly different functions), it is not a good idea to
+so. You should remember that the DC must register the DOMAIN#1b NetBIOS
+name. This is the name used by Windows clients to locate the DC.
+Windows clients do not distinguish between the DC and the DMB.
+For this reason, it is very wise to configure the Samba DC as the DMB.</P
+><P
+>Now back to the issue of configuring a Samba DC to use a mode other
+than "security = user". If a Samba host is configured to use
+another SMB server or DC in order to validate user connection
+requests, then it is a fact that some other machine on the network
+(the "password server") knows more about user than the Samba host.
+99% of the time, this other host is a domain controller. Now
+in order to operate in domain mode security, the "workgroup" parameter
+must be set to the name of the Windows NT domain (which already
+has a domain controller, right?)</P
+><P
+>Therefore configuring a Samba box as a DC for a domain that
+already by definition has a PDC is asking for trouble.
+Therefore, you should always configure the Samba DC to be the DMB
+for its domain.</P

+The term "Domain Controller" and those related to it refer to one specific

+prior to Windows NT Server 3.1 were sold by various companies and based on
+private extensions to the LAN Manager 2.1 protocol. Windows NT introduced
+Microsoft-specific ways of distributing the user authentication database.
+See DOMAIN.txt for examples of how Samba can participate in or create
+SMB domains based on shared authentication database schemes other than the
+Windows NT SAM.</P
+><P
+>Windows NT Server can be installed as either a plain file and print server
+(WORKGROUP workstation or server) or as a server that participates in Domain
+Control (DOMAIN member, Primary Domain controller or Backup Domain controller).
+The same is true for OS/2 Warp Server, Digital Pathworks and other similar
+products, all of which can participate in Domain Control along with Windows NT.</P
+><P
+>To many people these terms can be confusing, so let's try to clear the air.</P
+><P
+>Every Windows NT system (workstation or server) has a registry database.
+The registry contains entries that describe the initialization information
+for all services (the equivalent of Unix Daemons) that run within the Windows
+NT environment. The registry also contains entries that tell application
+software where to find dynamically loadable libraries that they depend upon.
+In fact, the registry contains entries that describes everything that anything
+may need to know to interact with the rest of the system.</P
+><P
+>The registry files can be located on any Windows NT machine by opening a
+command prompt and typing:</P
+><P
+><TT
+CLASS="PROMPT"
+>C:\WINNT\&#62;</TT
+> dir %SystemRoot%\System32\config</P
+><P
+>The environment variable %SystemRoot% value can be obtained by typing:</P
+><P
+><TT
+CLASS="PROMPT"
+>C:\WINNT&#62;</TT
+>echo %SystemRoot%</P
+><P
+>The active parts of the registry that you may want to be familiar with are
+the files called: default, system, software, sam and security.</P
+><P
+>In a domain environment, Microsoft Windows NT domain controllers participate
+in replication of the SAM and SECURITY files so that all controllers within
+the domain have an exactly identical copy of each.</P
+><P
+>The Microsoft Windows NT system is structured within a security model that
+says that all applications and services must authenticate themselves before
+they can obtain permission from the security manager to do what they set out
+to do.</P
+><P
+>The Windows NT User database also resides within the registry. This part of
+the registry contains the user's security identifier, home directory, group
+memberships, desktop profile, and so on.</P
+><P
+>Every Windows NT system (workstation as well as server) will have its own
+registry. Windows NT Servers that participate in Domain Security control
+have a database that they share in common - thus they do NOT own an
+independent full registry database of their own, as do Workstations and
+plain Servers.</P
+><P
+>The User database is called the SAM (Security Access Manager) database and
+is used for all user authentication as well as for authentication of inter-
+process authentication (i.e. to ensure that the service action a user has
+requested is permitted within the limits of that user's privileges).</P
+><P
+>The Samba team have produced a utility that can dump the Windows NT SAM into
+smbpasswd format: see ENCRYPTION.txt for information on smbpasswd and
+/pub/samba/pwdump on your nearest Samba mirror for the utility. This
+facility is useful but cannot be easily used to implement SAM replication
+to Samba systems.</P
+><P
+>Windows for Workgroups, Windows 95, and Windows NT Workstations and Servers
+can participate in a Domain security system that is controlled by Windows NT
+servers that have been correctly configured. Almost every domain will have
+ONE Primary Domain Controller (PDC). It is desirable that each domain will
+have at least one Backup Domain Controller (BDC).</P
+><P
+>The PDC and BDCs then participate in replication of the SAM database so that
+each Domain Controlling participant will have an up to date SAM component
+within its registry.</P

+>7.2. Background</H2
+><P
+>What is a Domain Controller? It is a machine that is able to answer
+logon requests from workstations in a Windows NT Domain. Whenever a
+user logs into a Windows NT Workstation, the workstation connects to a
+Domain Controller and asks him whether the username and password the
+user typed in is correct. The Domain Controller replies with a lot of
+information about the user, for example the place where the users
+profile is stored, the users full name of the user. All this
+information is stored in the NT user database, the so-called SAM.</P
+><P
+>There are two kinds of Domain Controller in a NT 4 compatible Domain:
+A Primary Domain Controller (PDC) and one or more Backup Domain
+Controllers (BDC). The PDC contains the master copy of the
+SAM. Whenever the SAM has to change, for example when a user changes
+his password, this change has to be done on the PDC. A Backup Domain
+Controller is a machine that maintains a read-only copy of the
+SAM. This way it is able to reply to logon requests and authenticate
+users in case the PDC is not available. During this time no changes to
+the SAM are possible. Whenever changes to the SAM are done on the PDC,
+all BDC receive the changes from the PDC.</P
+><P
+>Since version 2.2 Samba officially supports domain logons for all
+current Windows Clients, including Windows 2000 and XP. This text
+assumes the domain to be named SAMBA. To be able to act as a PDC, some
+parameters in the [global]-section of the smb.conf have to be set:</P
+><P
+><PRE
+CLASS="PROGRAMLISTING"
+>workgroup = SAMBA
+domain master = yes
+domain logons = yes</PRE
+></P
+><P
+>Several other things like a [homes] and a [netlogon] share also may be
+set along with settings for the profile path, the users home drive and
+others. This will not be covered in this document.</P

+NAME="AEN1130"

+>7.3. What qualifies a Domain Controller on the network?</H2
+><P
+>Every machine that is a Domain Controller for the domain SAMBA has to
+register the NetBIOS group name SAMBA#1c with the WINS server and/or
+by broadcast on the local network. The PDC also registers the unique
+NetBIOS name SAMBA#1b with the WINS server. The name type #1b is
+normally reserved for the domain master browser, a role that has
+nothing to do with anything related to authentication, but the
+Microsoft Domain implementation requires the domain master browser to
+be on the same machine as the PDC.</P

+>7.3.1. How does a Workstation find its domain controller?</H3
+><P
+>A NT workstation in the domain SAMBA that wants a local user to be
+authenticated has to find the domain controller for SAMBA. It does
+this by doing a NetBIOS name query for the group name SAMBA#1c. It
+assumes that each of the machines it gets back from the queries is a
+domain controller and can answer logon requests. To not open security
+holes both the workstation and the selected (TODO: How is the DC
+chosen) domain controller authenticate each other. After that the
+workstation sends the user's credentials (his name and password) to
+the domain controller, asking for approval.</P

+>Whenever a user wants to change his password, this has to be done on
+the PDC. To find the PDC, the workstation does a NetBIOS name query
+for SAMBA#1b, assuming this machine maintains the master copy of the
+SAM. The workstation contacts the PDC, both mutually authenticate and

->It's also possible that the server can't work out what user name to
-connect you as. To see if this is the problem add the line "user =
-USERNAME" to the [tmp] section of smb.conf where "USERNAME" is the
-username corresponding to the password you typed. If you find this
-fixes things you may need the username mapping option. </P
+>With version 2.2, no. The native NT SAM replication protocols have
+not yet been fully implemented. The Samba Team is working on
+understanding and implementing the protocols, but this work has not
+been finished for version 2.2.</P

->It might also be the case that your client only sends encrypted passwords
-and you have <B

->encrypt passwords = no</B

-Turn it back on to fix.</P
+>Can I get the benefits of a BDC with Samba? Yes. The main reason for
+implementing a BDC is availability. If the PDC is a Samba machine,
+a second Samba machine can be set up to
+service logon requests whenever the PDC is down.</P

+><P
+>Several things have to be done:</P
+><P
+></P
+><UL
+><LI
+><P
+>The domain SID has to be the same on the PDC and the BDC. This used to
+be stored in the file private/MACHINE.SID. This file is not created
+anymore since Samba 2.2.5 or even earlier. Nowadays the domain SID is
+stored in the file private/secrets.tdb. Simply copying the secrets.tdb
+from the PDC to the BDC does not work, as the BDC would
+generate a new SID for itself and override the domain SID with this
+new BDC SID.</P
+><P
+>To retrieve the domain SID from the PDC or an existing BDC and store it in the
+secrets.tdb, execute 'net rpc getsid' on the BDC.</P
+></LI
+><LI
+><P
+>The Unix user database has to be synchronized from the PDC to the
+BDC. This means that both the /etc/passwd and /etc/group have to be
+replicated from the PDC to the BDC. This can be done manually
+whenever changes are made, or the PDC is set up as a NIS master
+server and the BDC as a NIS slave server. To set up the BDC as a
+mere NIS client would not be enough, as the BDC would not be able to
+access its user database in case of a PDC failure.</P
+></LI
+><LI
+><P
+>The Samba password database in the file private/smbpasswd has to be
+replicated from the PDC to the BDC. This is a bit tricky, see the
+next section.</P
+></LI
+><LI
+><P
+>Any netlogon share has to be replicated from the PDC to the
+BDC. This can be done manually whenever login scripts are changed,
+or it can be done automatically together with the smbpasswd
+synchronization.</P
+></LI
+></UL
+><P
+>Finally, the BDC has to be found by the workstations. This can be done
+by setting</P
+><P
+><PRE
+CLASS="PROGRAMLISTING"
+>workgroup = samba
+domain master = no
+domain logons = yes</PRE
+></P
+><P
+>in the [global]-section of the smb.conf of the BDC. This makes the BDC
+only register the name SAMBA#1c with the WINS server. This is no
+problem as the name SAMBA#1c is a NetBIOS group name that is meant to
+be registered by more than one machine. The parameter 'domain master =
+no' forces the BDC not to register SAMBA#1b which as a unique NetBIOS
+name is reserved for the Primary Domain Controller.</P

><P
->Run the command <B
-CLASS="COMMAND"
->nmblookup -M TESTGROUP</B
-> where
-TESTGROUP is the name of the workgroup that your Samba server and
-Windows PCs belong to. You should get back the IP address of the
-master browser for that workgroup.</P
+>Replication of the smbpasswd file is sensitive. It has to be done
+whenever changes to the SAM are made. Every user's password change is
+done in the smbpasswd file and has to be replicated to the BDC. So
+replicating the smbpasswd file very often is necessary.</P
><P
->If you don't then the election process has failed. Wait a minute to
-see if it is just being slow then try again. If it still fails after
-that then look at the browsing options you have set in smb.conf. Make
-sure you have <B
-CLASS="COMMAND"
->preferred master = yes</B
-> to ensure that
-an election is held at startup.</P
+>As the smbpasswd file contains plain text password equivalents, it
+must not be sent unencrypted over the wire. The best way to set up
+smbpasswd replication from the PDC to the BDC is to use the utility
+rsync. rsync can use ssh as a transport. ssh itself can be set up to
+accept *only* rsync transfer without requiring the user to type a

+>9.2. Samba and Windows 2000 Domains</H2
+><P
+>Many people have asked regarding the state of Samba's ability to participate in
+a Windows 2000 Domain. Samba 3.0 is able to act as a member server of a Windows
+2000 domain operating in mixed or native mode.</P
+><P
+>There is much confusion between the circumstances that require a "mixed" mode
+Win2k DC and a when this host can be switched to "native" mode. A "mixed" mode
+Win2k domain controller is only needed if Windows NT BDCs must exist in the same
+domain. By default, a Win2k DC in "native" mode will still support
+NetBIOS and NTLMv1 for authentication of legacy clients such as Windows 9x and
+NT 4.0. Samba has the same requirements as a Windows NT 4.0 member server.</P
+><P
+>The steps for adding a Samba 2.2 host to a Win2k domain are the same as those
+for adding a Samba server to a Windows NT 4.0 domain. The only exception is that
+the "Server Manager" from NT 4 has been replaced by the "Active Directory Users and
+Computers" MMC (Microsoft Management Console) plugin.</P

+>9.3. Why is this better than security = server?</H2
+><P
+>Currently, domain security in Samba doesn't free you from
+ having to create local Unix users to represent the users attaching
+ to your server. This means that if domain user <TT
+CLASS="CONSTANT"
+>DOM\fred
+ </TT
+> attaches to your domain security Samba server, there needs
+ to be a local Unix user fred to represent that user in the Unix
+ filesystem. This is very similar to the older Samba security mode
+ <A
+HREF="smb.conf.5.html#SECURITYEQUALSSERVER"
+TARGET="_top"
+>security = server</A
+>,
+ where Samba would pass through the authentication request to a Windows
+ NT server in the same way as a Windows 95 or Windows 98 server would.
+ </P
+><P
+>Please refer to the <A
+HREF="winbind.html"
+TARGET="_top"
+>Winbind
+ paper</A
+> for information on a system to automatically
+ assign UNIX uids and gids to Windows NT Domain users and groups.
+ This code is available in development branches only at the moment,
+ but will be moved to release branches soon.</P
+><P
+>The advantage to domain-level security is that the
+ authentication in domain-level security is passed down the authenticated
+ RPC channel in exactly the same way that an NT server would do it. This
+ means Samba servers now participate in domain trust relationships in
+ exactly the same way NT servers do (i.e., you can add Samba servers into
+ a resource domain and have the authentication passed on from a resource
+ domain PDC to an account domain PDC.</P
+><P
+>In addition, with <B
+CLASS="COMMAND"
+>security = server</B
+> every Samba
+ daemon on a server has to keep a connection open to the
+ authenticating server for as long as that daemon lasts. This can drain
+ the connection resources on a Microsoft NT server and cause it to run
+ out of available connections. With <B
+CLASS="COMMAND"
+>security = domain</B
+>,
+ however, the Samba daemons connect to the PDC/BDC only for as long
+ as is necessary to authenticate the user, and then drop the connection,
+ thus conserving PDC connection resources.</P
+><P
+>And finally, acting in the same manner as an NT server
+ authenticating to a PDC means that as part of the authentication
+ reply, the Samba server gets the user identification information such
+ as the user SID, the list of NT groups the user belongs to, etc. All
+ this information will allow Samba to be extended in the future into
+ a mode the developers currently call appliance mode. In this mode,
+ no local Unix users will be necessary, and Samba will generate Unix
+ uids and gids from the information passed back from the PDC when a
+ user is authenticated, making a Samba server truly plug and play
+ in an NT domain environment. Watch for this code soon.</P

->10.3. Why is this better than security = server?</H2
-><P
->Currently, domain security in Samba doesn't free you from
- having to create local Unix users to represent the users attaching
- to your server. This means that if domain user <TT
-CLASS="CONSTANT"
->DOM\fred
- </TT
-> attaches to your domain security Samba server, there needs
- to be a local Unix user fred to represent that user in the Unix
- filesystem. This is very similar to the older Samba security mode
- <A
-HREF="smb.conf.5.html#SECURITYEQUALSSERVER"
-TARGET="_top"
->security = server</A
->,
- where Samba would pass through the authentication request to a Windows
- NT server in the same way as a Windows 95 or Windows 98 server would.
- </P
-><P
->Please refer to the <A
-HREF="winbind.html"
-TARGET="_top"
->Winbind
- paper</A
-> for information on a system to automatically
- assign UNIX uids and gids to Windows NT Domain users and groups.
- This code is available in development branches only at the moment,
- but will be moved to release branches soon.</P
-><P
->The advantage to domain-level security is that the
- authentication in domain-level security is passed down the authenticated
- RPC channel in exactly the same way that an NT server would do it. This
- means Samba servers now participate in domain trust relationships in
- exactly the same way NT servers do (i.e., you can add Samba servers into
- a resource domain and have the authentication passed on from a resource
- domain PDC to an account domain PDC.</P
-><P
->In addition, with <B
-CLASS="COMMAND"
->security = server</B
-> every Samba
- daemon on a server has to keep a connection open to the
- authenticating server for as long as that daemon lasts. This can drain
- the connection resources on a Microsoft NT server and cause it to run
- out of available connections. With <B
-CLASS="COMMAND"
->security = domain</B
->,
- however, the Samba daemons connect to the PDC/BDC only for as long
- as is necessary to authenticate the user, and then drop the connection,
- thus conserving PDC connection resources.</P
-><P
->And finally, acting in the same manner as an NT server
- authenticating to a PDC means that as part of the authentication
- reply, the Samba server gets the user identification information such
- as the user SID, the list of NT groups the user belongs to, etc. All
- this information will allow Samba to be extended in the future into
- a mode the developers currently call appliance mode. In this mode,
- no local Unix users will be necessary, and Samba will generate Unix
- uids and gids from the information passed back from the PDC when a
- user is authenticated, making a Samba server truly plug and play
- in an NT domain environment. Watch for this code soon.</P

CLASS="COMMAND"

- information in the binaries and allow you to attach gdb to the

- process for an NT workstation, first get the workstation to make the
- connection. Pressing ctrl-alt-delete and going down to the domain box
- is sufficient (at least, on the first time you join the domain) to
- generate a 'LsaEnumTrustedDomains'. Thereafter, the workstation
- maintains an open connection, and therefore there will be an smbd

->A domain and a workgroup are exactly the same thing in terms of network
-browsing. The difference is that a distributable authentication
-database is associated with a domain, for secure login access to a
-network. Also, different access rights can be granted to users if they
-successfully authenticate against a domain logon server (NT server and
-other systems based on NT server support this, as does at least Samba TNG now).</P
-><P
->The SMB client logging on to a domain has an expectation that every other
-server in the domain should accept the same authentication information.
-Network browsing functionality of domains and workgroups is
-identical and is explained in BROWSING.txt. It should be noted, that browsing
-is totally orthogonal to logon support.</P
-><P
->Issues related to the single-logon network model are discussed in this
-section. Samba supports domain logons, network logon scripts, and user
-profiles for MS Windows for workgroups and MS Windows 9X/ME clients
-which will be the focus of this section.</P
-><P
->When an SMB client in a domain wishes to logon it broadcast requests for a
-logon server. The first one to reply gets the job, and validates its
-password using whatever mechanism the Samba administrator has installed.
-It is possible (but very stupid) to create a domain where the user
-database is not shared between servers, i.e. they are effectively workgroup
-servers advertising themselves as participating in a domain. This
-demonstrates how authentication is quite different from but closely
-involved with domains.</P
-><P
->Using these features you can make your clients verify their logon via
-the Samba server; make clients run a batch file when they logon to
-the network and download their preferences, desktop and start menu.</P
-><P
->Before launching into the configuration instructions, it is
-worthwhile lookingat how a Windows 9x/ME client performs a logon:</P
-><P

- contains the NetBIOS name of the logon server to use in the format of

->There are a few comments to make in order to tie up some
-loose ends. There has been much debate over the issue of whether

-modes other than <TT
-CLASS="CONSTANT"
->USER</TT
->. The only security mode
-which will not work due to technical reasons is <TT
-CLASS="CONSTANT"
->SHARE</TT
->
-mode security. <TT
-CLASS="CONSTANT"
->DOMAIN</TT
-> and <TT
-CLASS="CONSTANT"
->SERVER</TT
->
-mode security is really just a variation on SMB user level security.</P
-><P
->Actually, this issue is also closely tied to the debate on whether
-or not Samba must be the domain master browser for its workgroup
-when operating as a DC. While it may technically be possible
-to configure a server as such (after all, browsing and domain logons
-are two distinctly different functions), it is not a good idea to
-so. You should remember that the DC must register the DOMAIN#1b NetBIOS
-name. This is the name used by Windows clients to locate the DC.
-Windows clients do not distinguish between the DC and the DMB.
-For this reason, it is very wise to configure the Samba DC as the DMB.</P
-><P
->Now back to the issue of configuring a Samba DC to use a mode other
-than "security = user". If a Samba host is configured to use
-another SMB server or DC in order to validate user connection
-requests, then it is a fact that some other machine on the network
-(the "password server") knows more about user than the Samba host.
-99% of the time, this other host is a domain controller. Now
-in order to operate in domain mode security, the "workgroup" parameter
-must be set to the name of the Windows NT domain (which already
-has a domain controller, right?)</P
-><P
->Therefore configuring a Samba box as a DC for a domain that
-already by definition has a PDC is asking for trouble.
-Therefore, you should always configure the Samba DC to be the DMB
-for its domain.</P

-The term "Domain Controller" and those related to it refer to one specific
-method of authentication that can underly an SMB domain. Domain Controllers
-prior to Windows NT Server 3.1 were sold by various companies and based on
-private extensions to the LAN Manager 2.1 protocol. Windows NT introduced
-Microsoft-specific ways of distributing the user authentication database.
-See DOMAIN.txt for examples of how Samba can participate in or create
-SMB domains based on shared authentication database schemes other than the
-Windows NT SAM.</P
-><P
->Windows NT Server can be installed as either a plain file and print server
-(WORKGROUP workstation or server) or as a server that participates in Domain
-Control (DOMAIN member, Primary Domain controller or Backup Domain controller).
-The same is true for OS/2 Warp Server, Digital Pathworks and other similar
-products, all of which can participate in Domain Control along with Windows NT.</P
-><P
->To many people these terms can be confusing, so let's try to clear the air.</P
-><P
->Every Windows NT system (workstation or server) has a registry database.
-The registry contains entries that describe the initialization information
-for all services (the equivalent of Unix Daemons) that run within the Windows
-NT environment. The registry also contains entries that tell application
-software where to find dynamically loadable libraries that they depend upon.
-In fact, the registry contains entries that describes everything that anything
-may need to know to interact with the rest of the system.</P
-><P
->The registry files can be located on any Windows NT machine by opening a
-command prompt and typing:</P
-><P
-><TT
-CLASS="PROMPT"
->C:\WINNT\&#62;</TT
-> dir %SystemRoot%\System32\config</P
-><P
->The environment variable %SystemRoot% value can be obtained by typing:</P
-><P
-><TT
-CLASS="PROMPT"
->C:\WINNT&#62;</TT
->echo %SystemRoot%</P
-><P
->The active parts of the registry that you may want to be familiar with are
-the files called: default, system, software, sam and security.</P
-><P
->In a domain environment, Microsoft Windows NT domain controllers participate
-in replication of the SAM and SECURITY files so that all controllers within
-the domain have an exactly identical copy of each.</P
-><P
->The Microsoft Windows NT system is structured within a security model that
-says that all applications and services must authenticate themselves before
-they can obtain permission from the security manager to do what they set out
-to do.</P
-><P
->The Windows NT User database also resides within the registry. This part of
-the registry contains the user's security identifier, home directory, group
-memberships, desktop profile, and so on.</P
-><P
->Every Windows NT system (workstation as well as server) will have its own
-registry. Windows NT Servers that participate in Domain Security control
-have a database that they share in common - thus they do NOT own an
-independent full registry database of their own, as do Workstations and
-plain Servers.</P
-><P
->The User database is called the SAM (Security Access Manager) database and
-is used for all user authentication as well as for authentication of inter-
-process authentication (i.e. to ensure that the service action a user has
-requested is permitted within the limits of that user's privileges).</P
-><P
->The Samba team have produced a utility that can dump the Windows NT SAM into
-smbpasswd format: see ENCRYPTION.txt for information on smbpasswd and
-/pub/samba/pwdump on your nearest Samba mirror for the utility. This
-facility is useful but cannot be easily used to implement SAM replication
-to Samba systems.</P
-><P
->Windows for Workgroups, Windows 95, and Windows NT Workstations and Servers
-can participate in a Domain security system that is controlled by Windows NT
-servers that have been correctly configured. Almost every domain will have
-ONE Primary Domain Controller (PDC). It is desirable that each domain will
-have at least one Backup Domain Controller (BDC).</P
-><P
->The PDC and BDCs then participate in replication of the SAM database so that
-each Domain Controlling participant will have an up to date SAM component
-within its registry.</P

->13.2. Background</H2
-><P
->What is a Domain Controller? It is a machine that is able to answer
-logon requests from workstations in a Windows NT Domain. Whenever a
-user logs into a Windows NT Workstation, the workstation connects to a
-Domain Controller and asks him whether the username and password the
-user typed in is correct. The Domain Controller replies with a lot of
-information about the user, for example the place where the users
-profile is stored, the users full name of the user. All this
-information is stored in the NT user database, the so-called SAM.</P
-><P
->There are two kinds of Domain Controller in a NT 4 compatible Domain:
-A Primary Domain Controller (PDC) and one or more Backup Domain
-Controllers (BDC). The PDC contains the master copy of the
-SAM. Whenever the SAM has to change, for example when a user changes
-his password, this change has to be done on the PDC. A Backup Domain
-Controller is a machine that maintains a read-only copy of the
-SAM. This way it is able to reply to logon requests and authenticate
-users in case the PDC is not available. During this time no changes to
-the SAM are possible. Whenever changes to the SAM are done on the PDC,
-all BDC receive the changes from the PDC.</P
-><P
->Since version 2.2 Samba officially supports domain logons for all
-current Windows Clients, including Windows 2000 and XP. This text
-assumes the domain to be named SAMBA. To be able to act as a PDC, some
-parameters in the [global]-section of the smb.conf have to be set:</P

><P
->Every machine that is a Domain Controller for the domain SAMBA has to
-register the NetBIOS group name SAMBA#1c with the WINS server and/or
-by broadcast on the local network. The PDC also registers the unique
-NetBIOS name SAMBA#1b with the WINS server. The name type #1b is
-normally reserved for the domain master browser, a role that has
-nothing to do with anything related to authentication, but the
-Microsoft Domain implementation requires the domain master browser to

->13.3.1. How does a Workstation find its domain controller?</H3
-><P
->A NT workstation in the domain SAMBA that wants a local user to be
-authenticated has to find the domain controller for SAMBA. It does
-this by doing a NetBIOS name query for the group name SAMBA#1c. It
-assumes that each of the machines it gets back from the queries is a
-domain controller and can answer logon requests. To not open security
-holes both the workstation and the selected (TODO: How is the DC
-chosen) domain controller authenticate each other. After that the
-workstation sends the user's credentials (his name and password) to
-the domain controller, asking for approval.</P

-been finished for version 2.2.</P

->Can I get the benefits of a BDC with Samba? Yes. The main reason for

-><UL
-><LI
-><P
->The domain SID has to be the same on the PDC and the BDC. This used to
-be stored in the file private/MACHINE.SID. This file is not created
-anymore since Samba 2.2.5 or even earlier. Nowadays the domain SID is
-stored in the file private/secrets.tdb. Simply copying the secrets.tdb
-from the PDC to the BDC does not work, as the BDC would
-generate a new SID for itself and override the domain SID with this
-new BDC SID.</P
-><P
->To retrieve the domain SID from the PDC or an existing BDC and store it in the
-secrets.tdb, execute 'net rpc getsid' on the BDC.</P
-></LI
-><LI
-><P
->The Unix user database has to be synchronized from the PDC to the
-BDC. This means that both the /etc/passwd and /etc/group have to be
-replicated from the PDC to the BDC. This can be done manually
-whenever changes are made, or the PDC is set up as a NIS master
-server and the BDC as a NIS slave server. To set up the BDC as a
-mere NIS client would not be enough, as the BDC would not be able to
-access its user database in case of a PDC failure.</P
-></LI
-><LI

-></LI
-><LI
-><P
->Any netlogon share has to be replicated from the PDC to the
-BDC. This can be done manually whenever login scripts are changed,

->in the [global]-section of the smb.conf of the BDC. This makes the BDC
-only register the name SAMBA#1c with the WINS server. This is no
-problem as the name SAMBA#1c is a NetBIOS group name that is meant to
-be registered by more than one machine. The parameter 'domain master =

->16.1. Overview of browsing</H2
-><P
->SMB networking provides a mechanism by which clients can access a list
-of machines in a network, a so-called "browse list". This list
-contains machines that are ready to offer file and/or print services
-to other machines within the network. Thus it does not include
-machines which aren't currently able to do server tasks. The browse
-list is heavily used by all SMB clients. Configuration of SMB
-browsing has been problematic for some Samba users, hence this
-document.</P
-><P
->Browsing will NOT work if name resolution from NetBIOS names to IP
-addresses does not function correctly. Use of a WINS server is highly
-recommended to aid the resolution of NetBIOS (SMB) names to IP addresses.
-WINS allows remote segment clients to obtain NetBIOS name_type information
-that can NOT be provided by any other means of name resolution.</P

->16.2. Browsing support in samba</H2
-><P
->Samba now fully supports browsing. The browsing is supported by nmbd
-and is also controlled by options in the smb.conf file (see smb.conf(5)).</P
-><P
->Samba can act as a local browse master for a workgroup and the ability
-for samba to support domain logons and scripts is now available. See
-DOMAIN.txt for more information on domain logons.</P
-><P
->Samba can also act as a domain master browser for a workgroup. This
-means that it will collate lists from local browse masters into a
-wide area network server list. In order for browse clients to
-resolve the names they may find in this list, it is recommended that
-both samba and your clients use a WINS server.</P
-><P
->Note that you should NOT set Samba to be the domain master for a
-workgroup that has the same name as an NT Domain: on each wide area
-network, you must only ever have one domain master browser per workgroup,
-regardless of whether it is NT, Samba or any other type of domain master
-that is providing this service.</P
-><P
->[Note that nmbd can be configured as a WINS server, but it is not
-necessary to specifically use samba as your WINS server. NTAS can
-be configured as your WINS server. In a mixed NT server and
-samba environment on a Wide Area Network, it is recommended that
-you use the NT server's WINS server capabilities. In a samba-only
-environment, it is recommended that you use one and only one nmbd
-as your WINS server].</P
-><P
->To get browsing to work you need to run nmbd as usual, but will need
-to use the "workgroup" option in smb.conf to control what workgroup
-Samba becomes a part of.</P
-><P
->Samba also has a useful option for a Samba server to offer itself for
-browsing on another subnet. It is recommended that this option is only
-used for 'unusual' purposes: announcements over the internet, for
-example. See "remote announce" in the smb.conf man page. </P

->16.3. Problem resolution</H2
-><P
->If something doesn't work then hopefully the log.nmb file will help
-you track down the problem. Try a debug level of 2 or 3 for finding
-problems. Also note that the current browse list usually gets stored
-in text form in a file called browse.dat.</P
-><P
->Note that if it doesn't work for you, then you should still be able to
-type the server name as \\SERVER in filemanager then hit enter and
-filemanager should display the list of available shares.</P
-><P
->Some people find browsing fails because they don't have the global
-"guest account" set to a valid account. Remember that the IPC$
-connection that lists the shares is done as guest, and thus you must
-have a valid guest account.</P
-><P
->Also, a lot of people are getting bitten by the problem of too many
-parameters on the command line of nmbd in inetd.conf. This trick is to
-not use spaces between the option and the parameter (eg: -d2 instead
-of -d 2), and to not use the -B and -N options. New versions of nmbd
-are now far more likely to correctly find your broadcast and network
-address, so in most cases these aren't needed.</P
-><P
->The other big problem people have is that their broadcast address,
-netmask or IP address is wrong (specified with the "interfaces" option
-in smb.conf)</P

->16.4. Browsing across subnets</H2
-><P
->With the release of Samba 1.9.17(alpha1 and above) Samba has been
-updated to enable it to support the replication of browse lists
-across subnet boundaries. New code and options have been added to
-achieve this. This section describes how to set this feature up
-in different settings.</P
-><P
->To see browse lists that span TCP/IP subnets (ie. networks separated
-by routers that don't pass broadcast traffic) you must set up at least
-one WINS server. The WINS server acts as a DNS for NetBIOS names, allowing
-NetBIOS name to IP address translation to be done by doing a direct
-query of the WINS server. This is done via a directed UDP packet on
-port 137 to the WINS server machine. The reason for a WINS server is
-that by default, all NetBIOS name to IP address translation is done
-by broadcasts from the querying machine. This means that machines
-on one subnet will not be able to resolve the names of machines on
-another subnet without using a WINS server.</P
-><P
->Remember, for browsing across subnets to work correctly, all machines,
-be they Windows 95, Windows NT, or Samba servers must have the IP address
-of a WINS server given to them by a DHCP server, or by manual configuration
-(for Win95 and WinNT, this is in the TCP/IP Properties, under Network
-settings) for Samba this is in the smb.conf file.</P

->16.4.1. How does cross subnet browsing work ?</H3
-><P
->Cross subnet browsing is a complicated dance, containing multiple
-moving parts. It has taken Microsoft several years to get the code
-that achieves this correct, and Samba lags behind in some areas.
-However, with the 1.9.17 release, Samba is capable of cross subnet
-browsing when configured correctly.</P
-><P

-><P
->Consisting of 3 subnets (1, 2, 3) connected by two routers
-(R1, R2) - these do not pass broadcasts. Subnet 1 has 5 machines
-on it, subnet 2 has 4 machines, subnet 3 has 4 machines. Assume
-for the moment that all these machines are configured to be in the
-same workgroup (for simplicities sake). Machine N1_C on subnet 1
-is configured as Domain Master Browser (ie. it will collate the
-browse lists for the workgroup). Machine N2_D is configured as
-WINS server and all the other machines are configured to register
-their NetBIOS names with it.</P
-><P
->As all these machines are booted up, elections for master browsers
-will take place on each of the three subnets. Assume that machine
-N1_C wins on subnet 1, N2_B wins on subnet 2, and N3_D wins on
-subnet 3 - these machines are known as local master browsers for
-their particular subnet. N1_C has an advantage in winning as the
-local master browser on subnet 1 as it is set up as Domain Master
-Browser.</P
+>20.2.2. Access via cvs</H3
><P
->On each of the three networks, machines that are configured to
-offer sharing services will broadcast that they are offering
-these services. The local master browser on each subnet will
-receive these broadcasts and keep a record of the fact that
-the machine is offering a service. This list of records is
-the basis of the browse list. For this case, assume that
-all the machines are configured to offer services so all machines
-will be on the browse list.</P
-><P
->For each network, the local master browser on that network is
-considered 'authoritative' for all the names it receives via
-local broadcast. This is because a machine seen by the local
-master browser via a local broadcast must be on the same
-network as the local master browser and thus is a 'trusted'
-and 'verifiable' resource. Machines on other networks that
-the local master browsers learn about when collating their
-browse lists have not been directly seen - these records are
-called 'non-authoritative'.</P

->Now examine subnet 2. As soon as N2_B has become the local

-(N2_D) for the IP address associated with the NetBIOS name
-WORKGROUP&gt;1B&lt;. This name was registerd by the Domain master
-browser (N1_C) with the WINS server as soon as it was booted.</P
-><P
->Once N2_B knows the address of the Domain master browser it
-tells it that is the local master browser for subnet 2 by
-sending a MasterAnnouncement packet as a UDP port 138 packet.
-It then synchronizes with it by doing a NetServerEnum2 call. This
-tells the Domain Master Browser to send it all the server

->To set up cross subnet browsing on a network containing machines

-Samba server to be the Domain Master Browser (note that this is *NOT*
-the same as a Primary Domain Controller, although in an NT Domain the
-same machine plays both roles). The role of a Domain master browser is
-to collate the browse lists from local master browsers on all the
-subnets that have a machine participating in the workgroup. Without
-one machine configured as a domain master browser each subnet would
-be an isolated workgroup, unable to see any machines on any other
-subnet. It is the presense of a domain master browser that makes
-cross subnet browsing possible for a workgroup.</P

+> of <TT
+CLASS="FILENAME"

><P
->Do not do this for more than one Samba server on each subnet,
-or they will war with each other over which is to be the local
-master browser.</P
+>Let me explain how it works on NT/W2K, to have this magic fade away.
+When installing NT/W2K on a computer, the installer program creates some users
+and groups. Notably the 'Administrators' group, and gives to that group some
+privileges like the ability to change the date and time or to kill any process
+(or close too) running on the local machine. The 'Administrator' user is a
+member of the 'Administrators' group, and thus 'inherit' the 'Administrators'
+group privileges. If a 'joe' user is created and become a member of the
+'Administrator' group, 'joe' has exactly the same rights as 'Administrator'.</P
><P
->The "local master" parameter allows Samba to act as a local master
-browser. The "preferred master" causes nmbd to force a browser
-election on startup and the "os level" parameter sets Samba high
-enough so that it should win any browser elections.</P
+>When a NT/W2K machine is joined to a domain, during that phase, the "Domain
+Administrators' group of the PDC is added to the 'Administrators' group of the
+workstation. Every members of the 'Domain Administrators' group 'inherit' the
+rights of the 'Administrators' group when logging on the workstation.</P
><P
->If you have an NT machine on the subnet that you wish to
-be the local master browser then you can disable Samba from
-becoming a local master browser by setting the following

-care, as if you have two hosts (whether they are windows 95 or NT or

+initgroups() reads the latter. Most system admins who know the ropes
+symlink /etc/group to /etc/logingroup (hard link doesn't work for reasons
+too stupid to go into here). initgroups() will complain if one of the
+groups you're in in /etc/logingroup has what it considers to be an invalid
+ID, which means outside the range [0..UID_MAX], where UID_MAX is (I think)
+60000 currently on HP-UX. This precludes -2 and 65534, the usual 'nobody'
+GIDs.</P

+>If you encounter this problem, make sure that the programs that are failing

-privileges like the ability to change the date and time or to kill any process
-(or close too) running on the local machine. The 'Administrator' user is a
-member of the 'Administrators' group, and thus 'inherit' the 'Administrators'
-group privileges. If a 'joe' user is created and become a member of the
-'Administrator' group, 'joe' has exactly the same rights as 'Administrator'.</P
+>This file contains a list of tests you can perform to validate your
+Samba server. It also tells you what the likely cause of the problem
+is if it fails any one of these steps. If it passes all these tests
+then it is probably working fine.</P
><P
->When a NT/W2K machine is joined to a domain, during that phase, the "Domain
-Administrators' group of the PDC is added to the 'Administrators' group of the
-workstation. Every members of the 'Domain Administrators' group 'inherit' the
-rights of the 'Administrators' group when logging on the workstation.</P
+>You should do ALL the tests, in the order shown. We have tried to
+carefully choose them so later tests only use capabilities verified in
+the earlier tests.</P
><P
->You are now wondering how to make some of your samba PDC users members of the
-'Domain Administrators' ? That's really easy.</P

-give access to a certain directory to some users who are member of a group on
-your samba PDC. Flag that group as a domain group by running:</P

-groups you're in in /etc/logingroup has what it considers to be an invalid
-ID, which means outside the range [0..UID_MAX], where UID_MAX is (I think)
-60000 currently on HP-UX. This precludes -2 and 65534, the usual 'nobody'

-If you run an old version of SCO Unix then you may need to get important

><P
->DNIX has a problem with seteuid() and setegid(). These routines are

-C library for some reason.</P
+>Run the command "smbclient -L BIGSERVER" on the unix box. You
+should get a list of available shares back. </P
><P
->For this reason Samba by default defines the macro NO_EID in the DNIX
-section of includes.h. This works around the problem in a limited way,
-but it is far from ideal, some things still won't work right.</P
+>If you get a error message containing the string "Bad password" then
+you probably have either an incorrect "hosts allow", "hosts deny" or
+"valid users" line in your smb.conf, or your guest account is not
+valid. Check what your guest account is using "testparm" and
+temporarily remove any "hosts allow", "hosts deny", "valid users" or
+"invalid users" lines.</P
><P
->
-To fix the problem properly you need to assemble the following two
-functions and then either add them to your C library or link them into
-Samba.</P
+>If you get a "connection refused" response then the smbd server may
+not be running. If you installed it in inetd.conf then you probably edited
+that file incorrectly. If you installed it as a daemon then check that
+it is running, and check that the netbios-ssn port is in a LISTEN
+state using "netstat -a".</P
><P
->
-put this in the file <TT
-CLASS="FILENAME"
->setegid.s</TT
->:</P
+>If you get a "session request failed" then the server refused the
+connection. If it says "Your server software is being unfriendly" then
+its probably because you have invalid command line parameters to smbd,
+or a similar fatal problem with the initial startup of smbd. Also
+check your config file (smb.conf) for syntax errors with "testparm"
+and that the various directories where samba keeps its log and lock
+files exist.</P
+><P
+>There are a number of reasons for which smbd may refuse or decline
+a session request. The most common of these involve one or more of
+the following smb.conf file entries:</P
><P
><PRE
CLASS="PROGRAMLISTING"
-> .globl _setegid

+ bind interfaces only = Yes</PRE
></P
><P
->put this in the file <TT
-CLASS="FILENAME"
->seteuid.s</TT
->:</P
+>In the above, no allowance has been made for any session requests that
+will automatically translate to the loopback adaptor address 127.0.0.1.
+To solve this problem change these lines to:</P
><P

><P
->after creating the above files you then assemble them using</P
+>Do NOT use the "bind interfaces only" parameter where you may wish to
+use the samba password change facility, or where smbclient may need to
+access local service for name resolution or for local resource
+connections. (Note: the "bind interfaces only" parameter deficiency
+where it will not allow connections to the loopback address will be
+fixed soon).</P
><P
-><B
+>Another common cause of these two errors is having something already running
+on port 139, such as Samba (ie: smbd is running from inetd already) or
+something like Digital's Pathworks. Check your inetd.conf file before trying
+to start smbd as a daemon, it can avoid a lot of frustration!</P
+><P
+>And yet another possible cause for failure of TEST 3 is when the subnet mask
+and / or broadcast address settings are incorrect. Please check that the
+network interface IP Address / Broadcast Address / Subnet Mask settings are
+correct and that Samba has correctly noted these in the log.nmb file.</P
