+ <para>This is the FAQ for Samba 2.2 as an NTDomain controller.
+ This document is derived from the origional FAQ that was built and
+ maintained by Gerald Carter
+ from the early days of Samba NTDomain development up until recently.
+ It is now being updated as significent changes are made to 2.2.0.</para>
+
+ <para>Please note it does not apply to Samba2.2alpha0, Samba2.2alpha1, Samba 2.0.7, TNG nor HEAD branch.
+ </para>
+ <para>I'll repeat, it does not apply to the current snapshot [ftp mirror]:/pub/samba/alpha/samba-2.2.0-alpha1.tar.gz, only to the to the current cvs.</para>

+ <para><emphasis>It should be noted that 2.2.0 in its pre-release form still has a few problems,
+ I'll try and keep this section current while things are still dynamic.
+ At the time of this update (November 13, 2000) the current state of play is :</emphasis></para>
+
+ <para>Comments here about W2K joining the domain apply only to Samba 2.2 from the CVS after November 27th. The
+ 'snapshot' release Samba2.2alpha1 does not work !!! See below on how to get a CVS tree.</para>
+
+ <para>Client Side creation of Machine accounts does work but is not complete.
+ Firstly, the <filename>add user script</> runs as the user who's
+ name was entered, not as root. Secondly, the machine name passed to the script (%U)
+ has an underscore at the end, not a '$'. One alternative is to use %m and add the $.
+ This method is documented in the <ulink url="samba-pdc-howto.html">HowTo</>.
+ And thirdly, it does not work with NT4ws.
+ </para>
+
+ <para>A W2K machine can join the domain. See the <ulink url="samba-pdc-howto.html">HowTo</>
+ which explains the process. The methods
+ described are 'work arounds' and should be regarded as temporary. Although I (drb)
+ have tested these procedures a number of people have had difficulty so there
+ may be other issues at work. JFM is aware of these
+ problems and will attend to them when he can.</para>
+
+ <para>A Domain Admin account is required and at present it appears that only root
+ is a suitable candidate.</para>
+
+ <para>Much of the related code does work. For example, if an NT is removed from the
+ domain and then rejoins, the <filename>Create a Computer Account in the Domain</> dialog
+ will let you reset the smbpasswd. That is you don't need to do it from
+ the unix box. However, at the present, you do need to have root as an
+ administrator and use the root user name and password.</para>
+
+ <para><emphasis>Actually I'm
+ not sure that last paragraph is correct ....</></para>
+
+ <para><command>Policies</> do work on a W2K machine. MS says that recent builds of
+ W2K dont observe an NT policy but it appears it does in 'legacy' mode.</para>
+
+</sect1>
+<sect1><title>Introduction</>
+ <para>This FAQ was origionally compiled by Jerry Carter (gc) chiefly dealing with the 'old head'
+ version of Samba and its NTDomain facilities. It is being rewritten by David Bannon (drb)
+ so that it addresses more accurately the Samba 2.2 planned for release late 2000. </para>
+
+ <para>This document probably still contains some material that does not apply to
+ Samba 2.2 but most (all?) of the really misleading stuff has been removed. Some
+ issues are not dealt with or are dealt with badly. Please send corrections and additions to
+ David Bannon at D.Bannon@latrobe.edu.au</para>
+
+ <para>Hopefully, as we all become familiar with the Samba 2.2 as a PDC this document will
+ become much more usefull.</para>

+
+ <para>There is a comprehensive Samba PDC <ulink url="samba-pdc-howto.html">HowTo</>
+ accessable from the samba web site
+ under 'Documentation'. Its currently located at <ulink url="http://bioserve.latrobe.edu.au/samba">
+ http://bioserve.latrobe.edu.au/samba</>. Read it.</para>
+</sect2>
+
+<sect2><title>What is a 'machine account' ?</title>
+ <para>Every NT, W2K or Samba machine that joins a Samba controlled domain must be known to
+ the Samba PDC. There are two entries required, one in (typically) <filename>/etc/passwd</>
+ and the other in (typically) <filename>/usr/local/samba/private/smbpasswd</>. Under
+ some circumstances these entries are made <link linkend=machineaccounts>manually</>, the
+ <ulink url="samba-pdc-howto.html">HowTo</> discusses ways of creating them automatically.</para>
+</sect2>
+
+
+<sect2><title>"The machine account for this computer either does not exist or is not accessable."</>
+
+ <para>When I try to join the domain I get the message "The machine account for this computer
+ either does not exist or is not accessable". Whats wrong ?</para>
+
+ <para>This problem is caused by the PDC not having a suitable machine account.
+ If you are using the <command>add user script =</> method to create accounts
+ then this would indicate that it has not worked. Ensure the domain admin user
+ system is working.</para>
+
+ <para>Alternatively if you are creating account entries manually then they have not been created
+ correctly. Make sure that you have the entry correct for the machine account in smbpasswd
+ file on the Samba PDC. If you added the account using an editor rather than using the smbpasswd utility,
+ make sure that the account name is the machine netbios name with a '$' appended to it
+ ( ie. computer_name$ ). There must be an entry in both /etc/passwd and
+ the smbpasswd file. Some people have reported that
+ inconsistent subnet masks between the Samba server and the NT client have caused this problem.
+ Make sure that these are consistent for both client and server.</para>
+</sect2>
+
+<sect2><title id=machineaccounts>How do I create machine accounts manually ?</title>
+
+ <para>This was the only option until recently, now in version 2.2 better means are available.
+ You might still need to do it manually for a couple of reasons. A machine account
+ consists of two entries (assuming a standard install and /etc/passwd use),
+ one in /etc/passwd and the other in /usr/local/samba/private/smbpasswd. The /etc/passwd
+ entry will list the machine name with a $ appended, won't have a passwd, will have a null
+ shell and no home directory. For example a machine called 'doppy' would have an /etc/passwd
+ entry like this :</para>
+
+ <para><command>doppy$:x:505:501:NTMachine:/dev/null:/bin/false</></para>
+
+ <para>On a linux system for example, you would typically add it like this :</para>
+
+ <para><command>adduser -g machines -c NTMachine -d /dev/null -s /bin/false -n
+ doppy$</command></para>
+
+ <para>Then you need to add that entry to smbpasswd, assuming you have a suitable
+ path to the <command>smbpasswd</> programme, do this :</para>
+
+ <para><command>smbpasswd -a -m doppy$</command></para>
+
+ <para>The entry will be created with a well known password, so any machine that
+ says its doppy could join the domain as long as it gets in first. So don't create
+ the accounts any earlier than you need them.</para>
+</sect2>
+
+<sect2><title>I cannot include a '$' in a machine name.</title>
+
+ <para>A 'machine name' in (typically) <filename>/etc/passwd</> consists
+ of the machine name with a '$' appended. FreeBSD (and other BSD systems ?)
+ won't create a user with a '$' in their name.</para>
+
+ <para>The problem is only in the program used to make the entry, once made, it works
+ perfectly. So create a user without the '$' and use <command>vipw</> to edit
+ the entry, adding the '$'. Or create the whole entry with vipw if you like,
+ make sure you use a unique uid !</para>
+</sect2>
+
+<sect2><title id=alreadyhaveconnection>I get told "You already have a connection to the Domain...." when creating a
+ machine account.</>
+
+ <para>This happens if you try to create a machine account from the machine itself
+ and use a user name that does not work (for whatever reason) and then try
+ another (possibly valid) user name.
+ Exit out of the network applet to close the initial connection and try again.</para>
+
+ <para>Further, if the machine is a already a 'member of a workgroup' that is the
+ same name as the domain you are joining (bad idea) you will get this message.
+ Change the workgroup name to something else, it does not matter what, reboot,
+ and try again.</para>
+</sect2>
+
+<sect2><title>I get told "Cannot join domain, the credentials supplied conflict
+ with an existing set.."</>
+ <para>This is the same basic problem as mentioned above, <link linkend=alreadyhaveconnection>
+ "You already have a connection..."</link></para>
+</sect2>
+
+<sect2><title>"The system can not log you on (C000019B)...."</>
+ <para>I joined the domain successfully but after upgrading to a newer version of the
+ Samba code I get the message, "The system can not log you on (C000019B), Please try a
+ gain or consult your system administrator" when attempting to logon.</para>
+
+ <para>This occurs when the domain SID stored in private/WORKGROUP.SID is changed.
+ For example, you remove the file and smbd automatically creates a new one.
+ Or you are swapping back and forth between versions 2.0.7, TNG and the HEAD branch
+ code (not recommended). The only way to correct the problem is to restore the
+ original domain SID or remove the domain client from the domain and rejoin.</para>

+ even after the user has logged out. Consider the following scenario.</para>
+<itemizedlist>
+ <listitem><para> user1 logs into the Windows NT machine. Therefore the

+</itemizedlist>
+
+ <para>However, since the NT box has maintained a connection to [homes] which was
+ previously set to \\server\user1, when the operating system attempts to
+ get the profile and if it can read users1's profile, will get it otherwise it
+ will return an error. You get the picture.</para>

+<sect1><title>Policies</title>
+
+<sect2><title>What are 'Policies' ?.</title>
+ <para>When a user logs onto the domain via a client machine, the PDC sends
+ the client machine a list of things contained in the 'policy' (if it exists).
+ This list may do things like suppress a splach screen, format the dates the way you
+ like them or perhaps remove locally stored profiles.</para>
+
+ <para>On a samba PDC this list is obtained from a file called <command>ntconfig.pol</>
+ and located in the <command>[netlogon]</>share. The file is created with a policy editor
+ and must be readable by anyone and writeable by only root. See <link linkend=policyeditor>

+<sect2><title id=policyeditor>What about Windows NT Policy Editor ?</title>
+
+ <para>To create or edit <command>ntconfig.pol</> you must use the NT Server
+ Policy Editor, <command>poledit.exe</> which is included with NT Server
+ but <emphasis>not NT Workstation</>. There is a Policy Editor on a NTws
+ but it is not suitable for creating <emphasis>Domain Policies</emphasis>.
+ Further, although the Windows 95
+ Policy Editor can be installed on an NT Workstation/Server, it will not
+ work with NT policies because the registry key that are set by the policy templates.
+ However, the files from the NT Server will run happily enough on an NTws.
+ You need <filename>poledit.exe, common.adm</> and <filename>winnt.adm</>. It is convenient
+ to put the two *.adm files in <filename>c:\winnt\inf</> which is where
+ the binary will look for them unless told otherwise. Note also that that
+ directory is 'hidden'.</para>
+
+ <para>The Windows NT policy editor is also included with the
+ Service Pack 3 (and later) for Windows NT 4.0. Extract the files using
+ <command>servicepackname /x</>, ie thats <command>Nt4sp6ai.exe /x</>
+ for service pack 6a.
+ The policy editor, <command>poledt.exe</> and the associated template files (*.adm) should
+ be extracted as well. It is also possible to downloaded the policy template
+ files for Office97 and get a copy of the policy editor. Another possible
+ location is with the Zero Administration Kit available for download from Microsoft.

+<sect1><title>Passwords</title>
+
+<sect2><title>What is password sync and should I use it ?</title>
+
+ <para>NTws users can change their domain password by pressing Ctrl-Alt-Del and
+ choosing 'Change Password'. By default however, this does not change the unix password
+ (typically in <filename>/etc/passwd or /etc/shadow</>). In lots of situations
+ thats OK, for example :</para>
+ <itemizedlist>
+ <listitem><para>The server is only accessible to the user via samba.</para></listitem>
+ <listitem><para>Pam_smb or similar is installed so other applications
+ still refer to the samba password.</></>
+ </itemizedlist>
+ <para>But sometimes you really do need to maintain two seperate password databases and
+ there are good reasons to keep then in sync. Trying to explain to users
+ that they need to change their passwords in two seperate places or use
+ two seperate passwords is not fun.</para>
+
+ <para>However do understand that setting up password sync is not without problems either.
+ The chief difficulty is the interface between Samba and the <command>passwd</> command,

+
+
+ <para>In a domain that has a number of servers you only need one password database.
+ The machines that don't have their own ask the PDC to check for them.
+ This will work fine for a domain controlled by either a Samba or NT machine.
+ The following lines in smb.conf are typical, 'password server' points to the
+ samba machine (or an NT) that has the password list : </para>
+
+ <programlisting>
+
+ [global]
+ ...
+ security = domain
+ workgroup = { Put your domain name here }
+ password server = { Put the ip of the PDC here }
+ encrypt passwords = yes
+ ...
+ </programlisting>
+
+ <para>The samba server in question will have to 'join the domain', that requires
+ the domain controller to have a machine account for it. This is no different
+ to the machine account requirements to allow a NTws to join the domain. For
+ example, if we want a unix box called <emphasis>sleepy</> to ask the PDC called <emphasis>grumpy</>
+ to do its authentication then <emphasis>grumpy</> will need an entry in its smbpasswd
+ (assuming it's also samba) that starts with <emphasis>sleepy$</>. It would have to be
+ created <link linkend=machineaccounts>manually</>. </para>
+
+ <para>If the domain is controlled by an NTServer then the "Server Manager for Domains"
+ tool must be used to add 'sleepy' to the domain list.</para>
+
+ <para>In either case we then join the domain. If the domain is called <emphasis>forest</>
+ then on sleepy we would join the domain by typing :</para>
+
+ <para><command>smbpasswd -j forest</command></para>
+
+ <para>Note that the directory where the smbpasswd file would be
+ located should exist as this is where smbd will generate the MACHINE.SID file. This
+ might be <filename>/usr/local/samba/private/FOREST.SLEEPY.SID</> and
+ it contains the trust account password for the domain member. The permissions are
+ (and should remain) "rw-------</para>
+
+
+ <para>Note the Samba Servers without the password list will most likely still need an account
+ for each user, this means a line in its <filename>/etc/passwd</filename>. Because authentication
+ is being handled at the domain level the
+ <filename>/etc/passwd</filename> line does not need a password.
+ If the shares being offered are not user specific, ie a common (read only ?)
+ area or perhaps just printing then the user's
+ <filename>/etc/passwd</filename> does not need a home directory. A typical
+ line in <filename>/etc/passwd</filename> for a server that allows domain users to
+ connect to the samba shares but does not offer a home share ('cos that's on the PDC)
+ and does not allow logon to the unix prompt would be like this :</para>

+<sect2><title>What are some diagnostics tools I can use to debug the domain logon process and where can I
+ find them? </title>
+
+ <para>One of the best diagnostic tools for debugging problems is Samba itself. You can use the -d
+ option for both smbd and nmbd to specifiy what 'debug level' at which to run. See the man
+ pages on smbd, nmbd and smb.conf for more information on debugging options. The debug
+ level can range from 1 (the default) to around 100 but a debug level of about 20 will
+ normally help you find any errors that samba is encountering. Another helpful method
+ of debugging is to compile samba using the gcc -g flag. This will include debug
+ information in the binaries and allow you to attch gdb to the running smbd / nmbd
+ process. In order to attach gdb to an smbd 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 process running (assuming that you
+ haven't set a really short smbd idle timeout) So, in between pressing ctrl alt
+ delete, and actually typing in your password, you can gdb attach and continue.</para>
