Comment 22 for bug 526464

Comparing the success and the failure logs attached by the bug reporter, I can see the following difference:

Success-log:
[2010/03/11 08:05:57, 3] libsmb/ntlmssp.c:ntlmssp_server_auth(739)
  Got user=[someuser] domain=[SOMEDOMAIN] workstation=[SERVER3] len1=24 len2=24
[2010/03/11 08:05:57, 2] auth/auth.c:check_ntlm_password(309)
  check_ntlm_password: authentication for user [someuser] -> [someuser] -> [SOMEDOMAIN+someuser] succeeded
------------------
Failure-log:
[2010/01/27 19:02:21, 3] libsmb/ntlmssp.c:ntlmssp_server_auth(739)
  Got user=[] domain=[] workstation=[SERVER3] len1=1 len2=0
[2010/01/27 19:02:22, 2] auth/auth.c:check_ntlm_password(319)
  check_ntlm_password: Authentication for user [someuser] -> [someuser] FAILED with error NT_STATUS_ACCESS_DENIED

The domain seems missing here?
------------------

Perhaps the wireshark trace will tell us better. Please attach the corresponding logs in case of failure _and_ success along with the wireshark output, so that tracing will be easier! Thanks!
