People sometimes tout threads as a uniformly good thing. They are very
nice in their place but are quite inappropriate for smbd. nmbd is
another matter, and multi-threading it would be very nice.
slower, less scalable, less portable and much less robust. The fact
that we use a separate process for each connection is one of Samba's
biggest advantages.

</p><p>
Andrew tried to write a test threads library for nmbd that used only
nasty to program cleanly due to the enormous amount of shared data (in
complex structures) between the processes. We can't rely on each
platform having a shared memory system.

Originally Andrew used recursion to simulate a multi-threaded
environment, which use the stack enormously and made for really
confusing debugging sessions. Luke Leighton rewrote it to use a
nameserv.h. It has all the detail but none of the on-the-wire
mess. This makes it ideal for using in disk or memory-based databases
for browsing and WINS support.

The syntax of a debugging log file is represented as:

Note that in the above example the function names are not listed on
the header line. That's because the example above was generated on an
SGI Indy, and the SGI compiler doesn't support the __FUNCTION__ macro.

This is a short document that describes some of the issues that
confront a SMB implementation on unix, and how Samba copes with
them. They may help people who are looking at unix<->PC

PC connectivity.

The SMB protocol has only a loose username concept. Early SMB
protocols (such as CORE and COREPLUS) have no username concept at
all. Even in later protocols clients often attempt operations
service%user syntax, the saving of session setup usernames for later
validation and the derivation of the username from the service name
(either directly or via the user= option).

The commonly used SMB protocols have no way of saying "you can't do
that because you don't own the file". They have, in fact, no concept
of file ownership at all.
There are several possible solutions to this problem, including
username mapping, and forcing a specific username for particular
shares.

Many SMB clients uppercase passwords before sending them. I have no
idea why they do this. Interestingly WfWg uppercases the password only
if the server is running a protocol greater than COREPLUS, so
smbpasswd file containing these password hashes is only readable
by the root user. See the documentation ENCRYPTION.txt for more
details.

opportunistic locking, and currently Samba has no support for it.

When a SMB client opens a file it asks for a particular "deny mode" to
be placed on the file. These modes (DENY_NONE, DENY_READ, DENY_WRITE,
DENY_ALL, DENY_FCB and DENY_DOS) specify what actions should be

A SMB session can run with several uids on the one socket. This
happens when a user connects to two shares with different
usernames. To cope with this the unix server needs to switch uids
</p><p>
Note that you can also get the "trapdoor uid" message for other
reasons. Please see the FAQ for details.

There is a convention that clients on sockets use high "unprivilaged"
port numbers (>1000) and connect to servers on low "privilaged" port
numbers. This is enforced in Unix as non-root users can't open a
back, but it goes to port 137 which the unix user can't listen
on. Interestingly WinNT3.1 got this right - it sends node status
responses back to the source port in the request.

On first joining the domain the session key could be computed by
anyone listening in on the network as the machine password has a well
known value. Until the machine is rebooted it will use this session
The password OWFs should NOT be sent over the network reversibly
encrypted. They should be sent using ARC4(Ks,md4(owf)) with the server
computing the same function using the owf values in the SAM.

SIDs and RIDs are well documented elsewhere.
</p><p>
A SID is an NT Security ID (see DOM_SID structure). They are of the form:
</p><table class="simplelist" border="0" summary="Simple list"><tr><td>revision-NN-SubAuth1-SubAuth2-SubAuth3... </td></tr><tr><td>revision-0xNNNNNNNNNNNN-SubAuth1-SubAuth2-SubAuth3...</td></tr></table><p>
currently, the SID revision is 1.
The Sub-Authorities are known as Relative IDs (RIDs).

of Group RIDs, part of the DOM_GID structure, in the USER_INFO_1
structure, in the LSA SAM Logon response.

One of the things that the 'new SAM' work has tried to face is both
compatibility with existing code, and a closer alignment to the SAMR
interface. I consider SAMR to be a 'primary customer' to the this work,
'conflicting' updates: Currently we don't deal with this (in passdb
or the new sam stuff), but the design is sufficiently flexible to 'deny'
a second update. I don't foresee locking records however.

Some subsystems in samba use different backends. These backends can be
either statically linked in to samba or available as a plugin. A subsystem
should have a function that allows a module to register itself. For example,
</pre><p>
This function will be called by the initialisation function of the module to
register itself.

The modules system compiles a list of initialisation functions for the
static modules of each subsystem. This is a define. For example,
it is here currently (from <tt class="filename">include/config.h</tt>):
</pre><p>
These functions should be called before the subsystem is used. That

Each module has an initialisation function. For modules that are
included with samba this name is '<i class="replaceable"><tt>subsystem</tt></i>_<i class="replaceable"><tt>backend</tt></i>_init'. For external modules (that will never be built-in, but only available as a module) this name is always 'init_module'. (In the case of modules included with samba, the configure system will add a #define subsystem_backend_init() init_module()).
The prototype for these functions is:
smb_register_passdb(PASSDB_INTERFACE_VERSION, "ldapsam_nua", pdb_init_ldapsam_nua);
return NT_STATUS_OK;

Some macros in configure.in generate the various defines and substs that
are necessary for the system to work correct. All modules that should
be built by default have to be added to the variable 'default_modules'.
</p><p>You must make sure all .c files that contain defines that can

This document describes how to make use the new RPC Pluggable Modules features
of Samba 3.0. This architecture was added to increase the maintainability of
Samba allowing RPC Pipes to be worked on separately from the main CVS branch.
The RPM architecture will also allow third-party vendors to add functionality
to Samba through plug-ins.

When an RPC call is sent to smbd, smbd tries to load a shared library by the
name <tt class="filename">librpc_<pipename>.so</tt> to handle the call if
it doesn't know how to handle the call internally. For instance, LSA calls

+ the real UNIX username, as many DOS clients send an all-uppercase
+ username. By default Samba tries all lowercase, followed by the
+ username with the first letter capitalized, and fails if the
+ username is not found on the UNIX machine.</p><p>If this parameter is set to non-zero the behavior changes.
+ This parameter is a number that specifies the number of uppercase
+ combinations to try while trying to determine the UNIX user name. The
+ higher the number the more combinations will be tried, but the slower
+ the discovery of usernames will be. Use this parameter when you have
+ strange usernames on your UNIX machine, such as <tt class="constant">AstrangeUser
+ </tt>.</p><p>Default: <b class="command">username level = 0</b></p><p>Example: <b class="command">username level = 5</b></p></dd><dt><span class="term"><a name="USERNAMEMAP"></a>username map (G)</span></dt><dd><p>This option allows you to specify a file containing
+ a mapping of usernames from the clients to the server. This can be
+ used for several purposes. The most common is to map usernames
+ that users use on DOS or Windows machines to those that the UNIX
+ box uses. The other is to map multiple users to a single username
+ so that they can more easily share files.</p><p>The map file is parsed line by line. Each line should
+ contain a single UNIX username on the left then a '=' followed
+ by a list of usernames on the right. The list of usernames on the
+ right may contain names of the form @group in which case they
+ will match any UNIX username in that group. The special client
+ name '*' is a wildcard and matches any name. Each line of the
+ map file may be up to 1023 characters long.</p><p>The file is processed on each line by taking the
+ supplied username and comparing it with each username on the right
+ hand side of the '=' signs. If the supplied name matches any of
+ the names on the right hand side then it is replaced with the name
+ on the left. Processing then continues with the next line.</p><p>If any line begins with a '#' or a ';' then it is ignored</p><p>If any line begins with an '!' then the processing
+ will stop after that line if a mapping was done by the line.
+ Otherwise mapping continues with every line being processed.
+ Using '!' is most useful when you have a wildcard mapping line
+ later in the file.</p><p>For example to map from the name <tt class="constant">admin</tt>
+ or <tt class="constant">administrator</tt> to the UNIX name <tt class="constant">
+ root</tt> you would use:</p><p><b class="command">root = admin administrator</b></p><p>Or to map anyone in the UNIX group <tt class="constant">system</tt>
+ to the UNIX name <tt class="constant">sys</tt> you would use:</p><p><b class="command">sys = @system</b></p><p>You can have as many mappings as you like in a username map file.</p><p>If your system supports the NIS NETGROUP option then
+ the netgroup database is checked before the <tt class="filename">/etc/group
+ </tt> database for matching groups.</p><p>You can map Windows usernames that have spaces in them
+ by using double quotes around the name. For example:</p><p><b class="command">tridge = "Andrew Tridgell"</b></p><p>would map the windows username "Andrew Tridgell" to the
+ unix username "tridge".</p><p>The following example would map mary and fred to the
+ unix user sys, and map the rest to guest. Note the use of the
+ '!' to tell Samba to stop processing if it gets a match on
+ that line.</p><pre class="programlisting">
+!sys = mary fred
+guest = *
+</pre><p>Note that the remapping is applied to all occurrences
+ of usernames. Thus if you connect to \\server\fred and <tt class="constant">
+ fred</tt> is remapped to <tt class="constant">mary</tt> then you
+ will actually be connecting to \\server\mary and will need to
+ supply a password suitable for <tt class="constant">mary</tt> not
+ <tt class="constant">fred</tt>. The only exception to this is the
+ username passed to the <a href="#PASSWORDSERVER"><i class="parameter"><tt>
+ password server</tt></i></a> (if you have one). The password
+ server will receive whatever username the client supplies without
+ modification.</p><p>Also note that no reverse mapping is done. The main effect

+ trouble deleting print jobs as PrintManager under WfWg will think
+ they don't own the print job.</p><p>Default: <span class="emphasis"><em>no username map</em></span></p><p>Example: <b class="command">username map = /usr/local/samba/lib/users.map</b></p></dd><dt><span class="term"><a name="USERS"></a>users (S)</span></dt><dd><p>Synonym for <a href="#USERNAME"><i class="parameter"><tt>
