samba - Nov 1997 - NT Domain Authentication - work in progress

Samba with experimental Login support for NT 3.5 and NT 4.0 Workstation
(stand-alone replacement for an NT Server Primary Domain Controller) is
currently at version 1.9.18alpha10.

[The Samba 1.9.18alpha series also supports oplocks (which enables SMB
clients to locally cache a file, unless someone else also wishes to access
it)].

I will be spending the next few days building up a series of packet traces
(my thanks to NEC R&D UK Ltd for sending me a replacement PSU for the NT
server!) using NetMonitor (netmon.exe, supplied with the NT Server
distribution, and with the MSDN Level 2 distribution).  If anyone else
wishes to assist with this process, please feel free to contact me
regarding the generation of NetMonitor traces of NT Workstation <-> NT
Server interactions. 

The documentation of the MS RPC Pipes is progressing: the section on the
RPC Pipes, which is an API command over the SMB "Transact" IPC$ pipe,
has
been developed.  Currently documented is part of the over-the-wire format
of the "Local Security Authority" interaction - \PIPE\ntlsa,
\PIPE\lsasrv
and \PIPE\lsass; and the "NT Net Logon" interaction - \PIPE\NETLOGON.

Comments on this document are welcomed, and should be made to the authors,
or on the CIFS digest (cifs@discuss.microsoft.com). The latest draft is at
http://mailhost.cb1.com/~lkcl/cifsntdomain.txt.


For those people interested in developing their own NT Domain Logon
Server; writing NT Domain PAMs; adding support for NT Domain Logons into
their unix or other operating system, the RPC pipe code (both client and
server) has been split into a separate library, and is at present being
issued under the GLPL.

For those people interested in crashing NT, please don't: this code was 
not written for that purpose.


please contact lkcl@switchboard.net direct for details on the NT Domain 
Authentication.  please contact samba-bugs@samba.anu.edu.au regarding any 
other samba issues.


regards,

luke (samba team member)
