[Samba] (no subject)

[Tom Elsesser]

I have a centos box using kernel 2.6.9-42.0.2.ELsmp that had a samba
server running very nicely until 2 days ago. Out of the blue, users can't
access any shares. We have 5 users and 6 shares, one of which is an MS
access database that gets the most use. I thought the smbpasswd database
may be corrupt so I replaced it with a backup, but no go. I deleted the
smbpasswd database, readded users, that didn't work either. Checking the
samba logs, I found this series of errors when trying to get to any samba
share:

[2007/12/19 08:28:18, 1] smbd/session.c:session_claim(143)
  pam_session rejected the session for tom [smb/19550/113]
[2007/12/19 08:28:18, 1] smbd/password.c:register_vuid(310)
  Failed to claim session for vuid=113
[2007/12/19 08:29:08, 0] auth/pampass.c:smb_pam_error_handler(73)
  smb_pam_error_handler: PAM: session setup failed : System error
[2007/12/19 08:29:08, 1] smbd/session.c:session_claim(143)
  pam_session rejected the session for tom [smb/21374/104]
[2007/12/19 08:29:08, 1] smbd/password.c:register_vuid(310)
  Failed to claim session for vuid=104

I can 'smbclient -L' to the workstations, and all other services (httpd,
sendmail, squid) are running as usual.  From my limited experience, it
seems authentication is whacked, but I can't flesh it out. ANy help is
appreciated.
