+What are DocBook documents doing in the Samba Distribution ?
+-----------------------------------------------------------
+By David Bannon, D.Bannon@latrobe.edu.au  November, 2000
+----------------------------------------------------------
+
+We are planning to convert some or all (?) of the samba docs to sgml DocBook to 
+make them easier to maintain and produce a nicer looking product.
+
+This short note (strange isn’t it how it always starts out as a short note and becomes a 
+long one ?) will explain very briefly how and why we are doing this.
+
+The format.
+--------------
+
+If you are new to sgml, regard an sgml file as 'source code'. You don't read it
+directly, use it to create other formats (like the txt and html included in ../txt and
+../html).
+
+Docbook is a particular sgml style, particularly suited to producing technical manuals. 
+In the two documents I have produced so far I have used DocBook 4.1, it seems that 
+products like RedHat Linux is still include only version 3.1, the differences are 
+minor. The Linux Documentation Project is using a modified version of 3.1 but are 
+really geared up to make multi paged documents, something we want to avoid for 
+logistic reasons. 
+
+The Output
+--------------
+Formatted html or xml is easily produced from a DocBook document, however I 
+had difficulty making a txt file directly ! It appears that the people who make 
+DocBook did not imagine anyone wanting to make plain text from a DocBook 
+document. At least one set of sgml tools appears to have decided that the easiest way 
+is to make the html and then convert that, this works fine.
+
+I have not had the need  to make man pages from a DocBook document yet, anyone 
+want to send me some pointers ??
+
+To make file handling and distribution easy I have opted for a single file or page per 
+document. In the Samba 2.2 distribution I made an html and a txt version of each sgml 
+file and placed that in the appropriate directory under ~/doc.
+
+The Tools
+-------------
+
+Any sgml document needs to be referred to a suitable style sheet (describing syntax) 
+and other sheets that tell the translating programmes how to do the translations. The 
+list of necessary ‘include’ files is a bit messy but once installed is pretty easy. 
+
+On one of my RedHat 6.2 systems I installed the following:
+* sgml-common (as an rpm)
+* docbook  (as an rpm)
+* stylesheets  (as an rpm)
+* jade  (as an rpm)
+* Docbook 4.1 from http://docbook.org
+* DSSSL 157 from http://nwalsh.com/docbook/dsssl/ 
+
+If you would be happy using DocBook 3.1 (and why not ?) then stop after the four 
+rpms. If you want to use 4.1 and the current DSSSL then you will need a bit of 
+manual editing of the catalog files.
+
+There are several downloadable descriptions of the DocBook syntax at the web sites 
+mentioned above. Note that a lot of the docs only talk about version 3.1 with 4.1 as an 
+add-on.
+
+In either case you will need to include in the html/docbook.dsl and most likely a 
+couple of ‘defines’ to achieve a suitable output. I made a local dsl file that I called 
+html.dsl that looks like this :
+
+
+<!DOCTYPE style-sheet PUBLIC "-//James Clark//DTD DSSSL Style Sheet//EN" [
+<!ENTITY dbstyle SYSTEM "/usr/lib/sgml/dsssl-157/docbook/html/docbook.dsl" 
+CDATA DSSSL>
+]>
+
+<style-sheet>
+<style-specification use="docbook">
+<style-specification-body>
+
+(define nochunks #t)			;; Dont make multiple pages
+(define rootchunk #t)			;; Do make a 'root' page
+(define %use-id-as-filename% #t)	;; Use book id as filename	
+(define %html-ext% ".html")		;; give it a proper html extension
+
+</style-specification-body>
+</style-specification>
+<external-specification id="docbook" document="dbstyle">
+</style-sheet>
+
+Note the top block that refers to where the dsssl-157 style sheets are installed, if you 
+don’t put them there make sure you edit the file. 
+
+To use this stylesheet, have it in your working directory along with your sgml files. 
+Jade does the actual conversion to html, call it like this :
+
+jade -t sgml -d html.dsl stuff.sgml
+
+To create the text version run the html through lynx :
+
+Lynx  -dump  -nolist  stuff.html  >  stuff.txt
+
+These instructions are crude by might help someone get going. Please feel free to 
+contact me if you have any questions or if you can correct any one of the many 
+mistakes I must have made above.

+
+    <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.

+     which explains the process. The methods

+    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>
+

+<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)

+
+	<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

+    and the other in (typically) <filename>/usr/local/samba/private/smbpasswd</>. Under 
+    some circumstances these entries are made <link linkend=machineaccounts>manually</>, the

+
+	<para>This problem is caused by the PDC not having a suitable machine account.

+	then this would indicate that it has not worked. Ensure the domain admin user

+
+	<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>

+
+    <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

+    </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, 
+	it can be a fiddle to set up and if the password the user has entered fails, 
+	the resulting errors are ambiguously reported
+	and the user is confused. Further, you need to take steps to ensure that users
+    only ever change their passwords via samba (or use <command>smbpasswd</>),

+
+
+	<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>

+	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>

+This document will show you one way of making Version 2.2.0  
+of Samba perform some of the tasks of a 
+NT Primary Domain Controller. The facilities described are built into Samba as a result of 
+development work done over a number of years by a large number of people. These facilities 
+are only just beginning to be officially supported and although they do appear to work reliably, 
+if you use them then you take the risks upon your self.  This document does not cover the
+developmental versions of Samba, particularly

+	</emphasis>
+	In our simple case every domain user should have an account on the PDC. The 
+	account may have a null shell if they are not allowed to log on to the unix 
+	prompt. Again they need an entry in both the <filename>/etc/passwd</filename> and
+	<filename>/usr/local/samba/private/smbpasswd</filename>. Again a password is 
+	not necessary in <filename>/etc/passwd</filename> but the location 
+	of the home directory is honoured. 
+	To make an entry for a user called Joe Blow you would typically do the following :</para>
+
+    <para><command>adduser -g users -c 'Joe Blow' -s /bin/false -n joeblow</command></para>
+
+    <para><command>smbpasswd -a joeblow</command></para>
+
+	<para>And you will prompted to enter a password for Joe. Ideally he will be 
+	hovering over your shoulder and will, when asked, type in a password of 
+	his choice. There are a number of scripts and systems to ease the migration of users
+	from somewhere to samba. Better start looking !</para>

+
+	<para>Certain operations demand that the logged on user has Administrator

+	doing maintenance tasks. It is very simple to appoint some users as Domain Admins, 
+	most likely yourself. Make
+	sure you trust the appointee !</para> 
+
+	<para>Samba 2.2 recognizes particular users as being
+	domain admins and tells the NTws when it thinks that it has got one logged on. 
+	In the smb.conf file we declare
+	that the <filename>Domain Admin users = user1 user2</filename>. 
+	Any user mentioned here will be treated as a Domain Admin by a NTws when 
+	logged onto the Domain. They will have full Administrator rights 
+	including the rights to change permissions on files and run the system 
+	utilities such as Disk Administrator.</para> 
+
+	<para>Further, and this is very new, they will be allowed to create a 
+	new machine account when first connecting a new NT or W2K machine to 
+	the domain. <emphasis>At present, ie pre-release, only a Domain Admin who
+	also happens to be root can do so. </emphasis></para>

+
+<sect1><title>Profiles</title> 
+
+	<para>NT Profiles should work if you have followed the setup so far. 
+	A user's profile contains a whole lot of their personal	settings, 
+	the contents of their desktop, personal 'My Documents' and so on. 
+	When they log off, all of the profile is copied to their directory 
+	on the server and is downloaded again when they logon on again, possibly 
+	on another client machine.</para> 
+
+	<para>Sounds great but can be a bit of a bug bear sometimes. Users let 
+	their profiles get too big and then complain about how long it takes 
+	to log on each time. This sample setup only supports NT profiles, 
+	rumor has it that it is also possible to do the same on Win95, my 
+	users don't know and I'm not telling them.</para>
+
+    <note><para>There is more info about Profiles (including for W95/98) 
+        in the <ulink url="samba-pdc-faq.html">FAQ</>.</para></note>
+</sect1>
+
+<sect1><title>Policies</title> 
+
+	<para>Policies are an easy way to make or enforce specific characteristics across your network. You create a ntconfig.pol
+	file and every time someone logs on with their NTws, the settings you put in ntconfig.pol are applied to the NTws.
+	Typical setting are things like making the date appear the way you want it (none of these 2 figure years here) or
+	maybe suppressing one of the splash screens. Perhaps you want to set the NTws so it does not keep users profiles
+	on the local machine. Cool. The only problem is making the ntconfig.pol file itself. You cannot use the policy editor
+	that comes with NTws.</para> 
+
+    <note><para>See the <ulink url="samba-pdc-faq.html">FAQ</> for pointers on how to get a suitable Policy Editor.</para></note>
+
+	<para>The Policy Editor (and associated files) will create a 
+	<filename>ntconfig.pol</filename> file using the 
+	parameters Microsoft thought of and parameters you specify by making your own 
+	template file.</para>
+
+	<para>In our example configuration here, Samba will expect to find 
+	the <filename>ntconfig.pol</filename> file in 
+	<filename>/usr/local/samba/netlogon</filename>. Needless to say (I hope !), 
+	it is vitally important that ordinary users don't have 
+	write permission to the Policy files.</para>
+</sect1>
+
+<sect1><title id=logonscript>Logon Scripts</title>
+
+	<para>In the sample config file above there is a line 
+	<filename>logon script = scripts\%U.bat</filename></para>
+
+	<note><para>Note that the slash is like this '\' not like this '/'. 
+	NT is happy with both, win95 is not !</para></note>
+
+	<para>This allows you to run a dos batch file every time someone logs on. The batch 
+	file is located on the server, in the sample install mentioned here, 
+	its in <filename>/usr/local/samba/netlogon/scripts</filename> and 
+	is named after the user with <filename>.bat</filename> appended, eg Joe
+	Blow's script is called <filename>/usr/local/samba/netlogon/scripts/joeblow.bat</filename>.</para>
+
+    <note><para>There is a suggestion that user names longer than 8 characters may cause
+	problems with some systems being unable to run logon scripts. This is confirmed in earlier
+    versions when connecting using W95, comments about other combinations ??</para></note>
+
+    <para>You could use a line like this <filename>logon script = default.bat</> and samba
+    will supply <filename>/usr/local/samba/netlogon/default.bat</> for any client and every
+    user. Maybe you could use %m and get a client machine dependant logon script.
+    You get the idea...</para>
+
+	<para>Note that the file is a dos batch file not a Unix script. It runs dos commands on the client 
+	computer with the logon	user's permissions. It must be a dos file with each line ending with 
+	the dos cr/lf not a nice clean newline. Generally,
+	its best to create the initial file on a DOS system and copy it across.</para>
+
+	<para>There is lots of very clever uses of the Samba replaceable variables such 
+	( %U = user, %G = primary group, %H = client machine, see the 'man 5 smb.conf') to 
+	give you control over which script runs when a particular person logs
+	on. (Gee, it would be nice to have a default.bat run when nothing else is available.)</para>
+
+	<para>Again, it is vitally important that ordinary users don't have write 
+	permission to other peoples, or even probably their own, logon script files.</para>
+
+	<para>A typical logon script is reproduced below. Note that it runs separate 
+	commands for win95 and NT, that's because NT has slightly different behaviour 
+	when using the <filename>net use ..</filename> command. Its useful for lots of 
+	other situations too. I	don't know what syntax to use for win98, I don't use it 
+	here.</para>

+
+	<para>So far our configuration assumes that ordinary users don't have unix logon access. A change
+	to the <link linkend=useraccount><filename>adduser</></> line above would allow unix logon 
+	but it would be with passwords that may 
+	be different from the NT logon. Clearly that won't suit everyone. Trying to explain to users
+	that they need to change their passwords in two seperate places is not fun. 
+	Further, even if they cannot do a unix logon there are other processes that 
+	might require authentication. We have a nice securely encrypted password in 
+	<filename>/usr/local/samba/private/smbpasswd</filename>, why not use it ?</para>

+<sect2><title>Using PAM</title>
+	<para>Pam enabled systems have a much better solution available. The Samba 
+	PDC server will	offer to authenticate domain users to other processes 
+	(either on this server or on the domain). With a suitable pam stack 
+	such as <ulink url="http://www.csn.ul.ie/~airlied/pam_smb/"> Pam_smb</ulink> 
+	you can get any pam aware application looking to the samba password and 
+	can leave the password field in <filename>/etc/shadow</filename>
+	or <filename>/etc/passwd</filename> invalid.</para>

+
+<sect2><title>Authenticating other Samba Servers</title>
+	<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.</para>
+
+    <para>To do so the Samba machine must be told to refer to the PDC and where the PDC is.

+<sect2><title>History</title>
+
+	<para>It might help you understand the limitations of the PDC in Samba if you
+	read something of its history. Well, the history as I understand it anyway.</para>
+
+	<para>For many years the Samba team have been developing Samba, some time ago 
+	a number of people, possibly lead by Luke Leighton started contributing NT 
+	PDC stuff. This was added to the 'head' stream (that would eventually
+	become the next version) and later to a seperate stream (NTDom). They did so 
+	much that eventually this development stream was so mutated that it could not 
+	be merged back into the main stream and was abandoned towards the end of 1999. 
+	And that was very sad because many users, myself include had become heavily
+	dependant on the NTController facilities it offered. Oh well...</para>
+
+	<para>The NTDom team continued on with their new found knowledge however and 
+	built the TNG stream. Intended to be carefully controlled so that it can be 
+	merged back into the main stream and benefiting from what they learnt, it is 
+	a very different product to the origional NTDom product. However, for a 
+    number of reasons, the merge did not take place and now TNG is being developed 
+    at <ulink url="http://www.samba-tng.org">http://www.samba-tng.org</>.</para>
+
+	<para>Now, the NTDom things that the main strean 2.0.x version does is based more 
+	on the old (initial version) abandoned code than on the TNG ideas. It appears 
+	that version 2.2.0 will also include an improved version of the 2.0.7 domain 
+	controller charactistics, not the TNG ways. The developers have indicated 
+	that 2.2.0 will be further developed incrementally and the ideas from TNG 
+	incorporated into it.</para>
+
+	<para>One more little wriggle is worth mentioning. At one stage the NTDom 
+	stream was called Samba 2.1.0-prealpha and similar names. This is most 
+	unfortunate because at least one book published advises people who want to 
+	use NTDom Samba to get version 2.1.0 or later. As main stream Samba will soon 
+	be called 2.2.0  and NOT officially supporting NTDom Controlling functions, 
+	the potential for confusion is certainly there.</para>
