Users should be educated about changes they may experience so that the change will be a -welcome one and not become an obstacle to the work they need to do. The following are some of the -factors that will go into a successful migration: -</para> - -<sect3> -<title>Domain Layout</title> - -<para> -Samba-3 can be configured as a domain controller, a back-up domain controller (probably best called -a secondary controller), a domain member, or as a stand-alone server. The Windows network security -domain context should be sized and scoped before implementation. Particular attention needs to be -paid to the location of the primary domain controller (PDC) as well as backup controllers (BDCs). -It should be noted that one way in which Samba-3 differs from Microsoft technology is that if one -chooses to use an LDAP authentication backend then the same database can be used by several different -domains. This means that in a complex organisation there can be a single LDAP database, that itself -can be distributed, that can simultaneously serve multiple domains (that can also be widely distributed). -</para> - -<para> -It is recommended that from a design perspective, the number of users per server, as well as the number -of servers, per domain should be scaled according to needs and should also consider server capacity -and network bandwidth. -</para> - -<para> -A physical network segment may house several domains, each of which may span multiple network segments. -Where domains span routed network segments it is most advisable to consider and test the performance -implications of the design and layout of a network. A Centrally located domain controller that is being -designed to serve mulitple routed network segments may result in severe performance problems if the -response time (eg: ping timing) between the remote segment and the PDC is more than 100 ms. In situations -where the delay is too long it is highly recommended to locate a backup controller (BDC) to serve as -the local authentication and access control server. -</para> -</sect3> - -<sect3> -<title>Server Share and Directory Layout</title> - -<para> -There are few cardinal rules to effective network design that can be broken with impunity. -The most important rule of effective network management is that simplicity is king in every -well controlled network. Every part of the infrastructure must be managed, the more complex -it is, the greater will be the demand of keeping systems secure and functional. -</para> - -<para> -The nature of the data that must be stored needs to be born in mind when deciding how many -shares must be created. The physical disk space layout should also be taken into account -when designing where share points will be created. Keep in mind that all data needs to be -backed up, thus the simpler the disk layout the easier it will be to keep track of what must -be backed up to tape or other off-line storage medium. Always plan and implement for minimum -maintenance. Leave nothing to chance in your design, above all, do not leave backups to chance: -Backup and test, validate every backup, create a disaster recovery plan and prove that it works. -</para> - -<para> -Users should be grouped according to data access control needs. File and directory access -is best controlled via group permissions and the use of the "sticky bit" on group controlled -directories may substantially avoid file access complaints from samba share users. -</para> - -<para> -Many network administrators who are new to the game will attempt to use elaborate techniques -to set access controls, on files, directories, shares, as well as in share definitions. -There is the ever present danger that that administrator's successor will not understand the -complex mess that has been inherited. Remember, apparent job security through complex design -and implementation may ultimately cause loss of operations and downtime to users as the new -administrator learns to untangle your web. Keep access controls simple and effective and -make sure that users will never be interrupted by the stupidity of complexity. -</para> -</sect3> - -<sect3> -<title>Logon Scripts</title> - -<para> -Please refer to the section of this document on Advanced Network Adminsitration for information -regarding the network logon script options for Samba-3. Logon scripts can help to ensure that -all users gain share and printer connections they need. -</para> - -<para> -Logon scripts can be created on-the-fly so that all commands executed are specific to the -rights and privilidges granted to the user.

In order - to allow "no permissions" to be seen and modified then Samba - overloads the NT <command>"Take Ownership"</command> ACL attribute - (which has no meaning in UNIX) and reports a component with - no permissions as having the NT <command>"O"</command> bit set. - This was chosen of course to make it look like a zero, meaning - zero permissions. More details on the decision behind this will - be given below.</para> - </sect2> - - <sect2> - <title>Directory Permissions</title> - - <para>Directories on an NT NTFS file system have two - different sets of permissions.

This means that you can only - manipulate the current user/group/world permissions listed in - the dialog box.

SMB messaging may be implemented using NetBIOS or -without 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. -</para> - -<para> -Normally, only unicast UDP messaging can be forwarded by routers.

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 -<command>remote announce</command> and the <command>remote browse sync</command> -parameters to your <filename>smb.conf</filename> file. -</para> - -<para> -If only one WINS server is used for an entire multi-segment network then -the use of the <command>remote announce</command> and the -<command>remote browse sync</command> parameters should NOT be necessary. -</para> - -<para> -As of Samba 3 WINS replication is being worked on. The bulk of the code has -been committed, but it still needs maturation. -</para> - -<para> -Right now samba WINS does not support MS-WINS replication. This means that -when setting up Samba as a WINS server there must only be one <filename>nmbd</filename> 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 -<command>remote browse sync</command> and <command>remote announce</command> -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). -</para> - -<para> -Lastly, take note that browse lists are a collection of unreliable broadcast -messages that are repeated at intervals of not more than 15 minutes.

In such situations Samba provides a means by -which the samba server name may be forcibly injected into the browse -list of a remote MS Windows network (using the -<command>remote announce</command> parameter). -</para> - -<para> -Where a WINS server is used, the MS Windows client will use UDP -unicast to register with the WINS server. Such packets can be routed -and thus WINS allows name resolution to function across routed networks. -</para> - -<para> -During the startup process an election will take place to create a -local master browser if one does not already exist. On each NetBIOS network -one machine will be elected to function as the domain master browser. This -domain browsing has nothing to do with MS security domain control. -Instead, the domain master browser serves the role of contacting each local -master browser (found by asking WINS or from LMHOSTS) and exchanging browse -list contents. This way every master browser will eventually obtain a complete -list of all machines that are on the network. Every 11-15 minutes an election -is held to determine which machine will be the master browser.

This effectively bridges -two networks that are separated by routers. The two remote -networks may use either broadcast based name resolution or WINS -based name resolution, but it should be noted that the <command>remote -browse sync</command> parameter provides browse list synchronisation - and -that is distinct from name to address resolution, in other -words, for cross subnet browsing to function correctly it is -essential that a name to address resolution mechanism be provided. -This mechanism could be via DNS, <filename>/etc/hosts</filename>, -and so on. -</para> - -<sect2> -<title>Setting up WORKGROUP Browsing</title> - -<para> -To set up cross subnet browsing on a network containing machines -in up to be in a WORKGROUP, not an NT Domain you need to set up one -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).

We present - <emphasis>winbind</emphasis>, a component of the Samba suite - of programs as a solution to the unified logon problem. Winbind - uses a UNIX implementation - of Microsoft RPC calls, Pluggable Authentication Modules, and the Name - Service Switch to allow Windows NT domain users to appear and operate - as UNIX users on a UNIX machine. This paper describes the winbind - system, explaining the functionality it provides, how it is configured, - and how it works internally.</para> -</sect1> - - -<sect1> - <title>Introduction</title> - - <para>It is well known that UNIX and Microsoft Windows NT have - different models for representing user and group information and - use different technologies for implementing them. This fact has - made it difficult to integrate the two systems in a satisfactory - manner.</para> - - <para>One common solution in use today has been to create - identically named user accounts on both the UNIX and Windows systems - and use the Samba suite of programs to provide file and print services - between the two. This solution is far from perfect however, as - adding and deleting users on both sets of machines becomes a chore - and two sets of passwords are required both of which - can lead to synchronization problems between the UNIX and Windows - systems and confusion for users.</para> - - <para>We divide the unified logon problem for UNIX machines into - three smaller problems:</para> - - <itemizedlist> - <listitem><para>Obtaining Windows NT user and group information - </para></listitem> - - <listitem><para>Authenticating Windows NT users - </para></listitem> - - <listitem><para>Password changing for Windows NT users - </para></listitem> - </itemizedlist> - - - <para>Ideally, a prospective solution to the unified logon problem - would satisfy all the above components without duplication of - information on the UNIX machines and without creating additional - tasks for the system administrator when maintaining users and - groups on either system. The winbind system provides a simple - and elegant solution to all three components of the unified logon - problem.</para> -</sect1> - - -<sect1> - <title>What Winbind Provides</title> - - <para>Winbind unifies UNIX and Windows NT account management by - allowing a UNIX box to become a full member of a NT domain. Once - this is done the UNIX box will see NT users and groups as if - they were native UNIX users and groups, allowing the NT domain - to be used in much the same manner that NIS+ is used within - UNIX-only environments.</para> - - <para>The end result is that whenever any - program on the UNIX machine asks the operating system to lookup - a user or group name, the query will be resolved by asking the - NT domain controller for the specified domain to do the lookup. - Because Winbind hooks into the operating system at a low level - (via the NSS name resolution modules in the C library) this - redirection to the NT domain controller is completely - transparent.</para> - - <para>Users on the UNIX machine can then use NT user and group - names as they would use "native" UNIX names. They can chown files - so that they are owned by NT domain users or even login to the - UNIX machine and run a UNIX X-Window session as a domain user.</para> - - <para>The only obvious indication that Winbind is being used is - that user and group names take the form DOMAIN\user and - DOMAIN\group. This is necessary as it allows Winbind to determine - that redirection to a domain controller is wanted for a particular - lookup and which trusted domain is being referenced.</para> - - <para>Additionally, Winbind provides an authentication service - that hooks into the Pluggable Authentication Modules (PAM) system - to provide authentication via a NT domain to any PAM enabled - applications. This capability solves the problem of synchronizing - passwords between systems since all passwords are stored in a single - location (on the domain controller).</para> - - <sect2> - <title>Target Uses</title> - - <para>Winbind is targeted at organizations that have an - existing NT based domain infrastructure into which they wish - to put UNIX workstations or servers. Winbind will allow these - organizations to deploy UNIX workstations without having to - maintain a separate account infrastructure. This greatly - simplifies the administrative overhead of deploying UNIX - workstations into a NT based organization.</para> - - <para>Another interesting way in which we expect Winbind to - be used is as a central part of UNIX based appliances. Appliances - that provide file and print services to Microsoft based networks - will be able to use Winbind to provide seamless integration of - the appliance into the domain.</para> - </sect2> -</sect1> - - - -<sect1> - <title>How Winbind Works</title> - - <para>The winbind system is designed around a client/server - architecture. A long running <command>winbindd</command> daemon - listens on a UNIX domain socket waiting for requests - to arrive. These requests are generated by the NSS and PAM - clients and processed sequentially.</para> - - <para>The technologies used to implement winbind are described - in detail below.</para> - - <sect2> - <title>Microsoft Remote Procedure Calls</title> - - <para>Over the last few years, efforts have been underway - by various Samba Team members to decode various aspects of - the Microsoft Remote Procedure Call (MSRPC) system. This - system is used for most network related operations between - Windows NT machines including remote management, user authentication - and print spooling. Although initially this work was done - to aid the implementation of Primary Domain Controller (PDC) - functionality in Samba, it has also yielded a body of code which - can be used for other purposes.</para> - - <para>Winbind uses various MSRPC calls to enumerate domain users - and groups and to obtain detailed information about individual - users or groups. Other MSRPC calls can be used to authenticate - NT domain users and to change user passwords. By directly querying - a Windows PDC for user and group information, winbind maps the - NT account information onto UNIX user and group names.</para> - </sect2> - - <sect2> - <title>Microsoft Active Directory Services</title> - - <para> - Since late 2001, Samba has gained the ability to - interact with Microsoft Windows 2000 using its 'Native - Mode' protocols, rather than the NT4 RPC services. - Using LDAP and Kerberos, a domain member running - winbind can enumerate users and groups in exactly the - same way as a Win2k client would, and in so doing - provide a much more efficient and - effective winbind implementation. - </para> - </sect2> - - <sect2> - <title>Name Service Switch</title> - - <para>The Name Service Switch, or NSS, is a feature that is - present in many UNIX operating systems. It allows system - information such as hostnames, mail aliases and user information - to be resolved from different sources. For example, a standalone - UNIX workstation may resolve system information from a series of - flat files stored on the local filesystem. A networked workstation - may first attempt to resolve system information from local files, - and then consult a NIS database for user information or a DNS server - for hostname information.</para> - - <para>The NSS application programming interface allows winbind - to present itself as a source of system information when - resolving UNIX usernames and groups. Winbind uses this interface, - and information obtained from a Windows NT server using MSRPC - calls to provide a new source of account enumeration. Using standard - UNIX library calls, one can enumerate the users and groups on - a UNIX machine running winbind and see all users and groups in - a NT domain plus any trusted domain as though they were local - users and groups.</para> - - <para>The primary control file for NSS is - <filename>/etc/nsswitch.conf</filename>. - When a UNIX application makes a request to do a lookup - the C library looks in <filename>/etc/nsswitch.conf</filename> - for a line which matches the service type being requested, for - example the "passwd" service type is used when user or group names - are looked up. This config line species which implementations - of that service should be tried and in what order. If the passwd - config line is:</para> - - <para><command>passwd: files example</command></para> - - <para>then the C library will first load a module called - <filename>/lib/libnss_files.so</filename> followed by - the module <filename>/lib/libnss_example.so</filename>. The - C library will dynamically load each of these modules in turn - and call resolver functions within the modules to try to resolve - the request. Once the request is resolved the C library returns the - result to the application.</para> - - <para>This NSS interface provides a very easy way for Winbind - to hook into the operating system. All that needs to be done - is to put <filename>libnss_winbind.so</filename> in <filename>/lib/</filename> - then add "winbind" into <filename>/etc/nsswitch.conf</filename> at - the appropriate place. The C library will then call Winbind to - resolve user and group names.</para> - </sect2> - - <sect2> - <title>Pluggable Authentication Modules</title> - - <para>Pluggable Authentication Modules, also known as PAM, - is a system for abstracting authentication and authorization - technologies. With a PAM module it is possible to specify different - authentication methods for different system applications without - having to recompile these applications. PAM is also useful - for implementing a particular policy for authorization. For example, - a system administrator may only allow console logins from users - stored in the local password file but only allow users resolved from - a NIS database to log in over the network.</para> - - <para>Winbind uses the authentication management and password - management PAM interface to integrate Windows NT users into a - UNIX system. This allows Windows NT users to log in to a UNIX - machine and be authenticated against a suitable Primary Domain - Controller. These users can also change their passwords and have - this change take effect directly on the Primary Domain Controller. - </para> - - <para>PAM is configured by providing control files in the directory - <filename>/etc/pam.d/</filename> for each of the services that - require authentication. When an authentication request is made - by an application the PAM code in the C library looks up this - control file to determine what modules to load to do the - authentication check and in what order. This interface makes adding - a new authentication service for Winbind very easy, all that needs - to be done is that the <filename>pam_winbind.so</filename> module - is copied to <filename>/lib/security/</filename> and the PAM - control files for relevant services are updated to allow - authentication via winbind. See the PAM documentation - for more details.</para> - </sect2> - - - <sect2> - <title>User and Group ID Allocation</title> - - <para>When a user or group is created under Windows NT - is it allocated a numerical relative identifier (RID). This is - slightly different to UNIX which has a range of numbers that are - used to identify users, and the same range in which to identify - groups. It is winbind's job to convert RIDs to UNIX id numbers and - vice versa. When winbind is configured it is given part of the UNIX - user id space and a part of the UNIX group id space in which to - store Windows NT users and groups. If a Windows NT user is - resolved for the first time, it is allocated the next UNIX id from - the range. The same process applies for Windows NT groups. Over - time, winbind will have mapped all Windows NT users and groups - to UNIX user ids and group ids.</para> - - <para>The results of this mapping are stored persistently in - an ID mapping database held in a tdb database). This ensures that - RIDs are mapped to UNIX IDs in a consistent way.</para> - </sect2> - - - <sect2> - <title>Result Caching</title> - - <para>An active system can generate a lot of user and group - name lookups. To reduce the network cost of these lookups winbind - uses a caching scheme based on the SAM sequence number supplied - by NT domain controllers. User or group information returned - by a PDC is cached by winbind along with a sequence number also - returned by the PDC. This sequence number is incremented by - Windows NT whenever any user or group information is modified. If - a cached entry has expired, the sequence number is requested from - the PDC and compared against the sequence number of the cached entry. - If the sequence numbers do not match, then the cached information - is discarded and up to date information is requested directly - from the PDC.</para> - </sect2> -</sect1> - - -<sect1> - <title>Installation and Configuration</title> - -<para> -Many thanks to John Trostel <ulink -url="mailto:jtrostel@snapserver.com">jtrostel@snapserver.com</ulink> -for providing the HOWTO for this section. -</para> - -<para> -This HOWTO describes how to get winbind services up and running -to control access and authenticate users on your Linux box using -the winbind services which come with SAMBA 2.2.2. -</para> - -<sect2> -<title>Introduction</title> - -<para> -This HOWTO describes the procedures used to get winbind up and -running on my RedHat 7.1 system.
