Description LarsE 2009-04-18 13:20:03 UTC
The README says:

the NTLM over HTTP protocol is completed undocumented by Microsoft but has been reverse engineered and described at the following URL:


Since 2007 this is incorrect. Microsoft have documented all NTLM related stuff.
All Windows Communicatations Protocols are documented here:


You can download a full zip will all PDFs for all Windows Communication Protocols (about 220 Mb download). You can also download the PDFs individually.

More specifically the specifications relating to NTLM are:

MS-NLMP:  Main document describing NTLM v1, NTLM v2. etc.

MS-NTHT: NTLM over HTTP protocol

MS-NNTP: Specifies the use of NTLM authentication by NNTP (Network News Transfer Protocol)

MS-POP3: NTML for use with POP3

MS-SMTP: NTML for use with SMTP

The above - and nothing else - should be considered the official documentation for NTLM, imho.

Reassigning this bug to the default assignee since Jerry is no longer directly involved in Samba development.
Comment 2 Lars Müller 2014-04-21 15:39:07 UTC
Authentication via NTLM is no longer the main protocol today.

Instead we encourage people ti use Apache mod_auth_kerb

Please reopen if you think this should be documented better.  In that case please add your patch or better a git pull request.
