samba - Feb 2002 - Failure with authentication using Winbind and SMTP

Hi, my name is Julio Rojas and I've trying to get my Linux (RedHat 7.2)
Email Server using Sendmail to use my NT Domain account database. To accomplish
this we have tried with Winbind and it has worked for longins at the server and
for POP3 authentication, but we haven't been succesful at SMTP
authentication. All the emails sent to my Linux server are rejected with the
message USER UNKNOWN. The following is an example of my NT server trying to send
an email to my Linux server:

SMTP (560) Trying aiur.uft.edu.ve (0)
SMTP (560) Connect aiur.uft.edu.ve [200.35.85.219:25] (2)
SMTP (560) 220 aiur.uft.edu.ve ESMTP Sendmail 8.11.6/8.11.6; Thu, 14 Feb 2002

SMTP (560) >QUIT
SMTP (560) 221 2.0.0 aiur.uft.edu.ve closing connection
SMTP (560) Creating message from Postmaster


First of all, is there any way of removing the domain name at the user name
(RED-UFT)? And the SMTP server is working fine with local Linux users, it just
doesn't work with Winbind.

Here is the PAM configuration file for SMTP. We have made it after the one that
works for POP3:

#%PAM-1.0
auth       sufficient /lib/security/pam_winbind.so
auth       required /lib/security/pam_pwdb.so use_first_pass shadow nullok
account    required /lib/security/pam_winbind.so

Can you help us??? Thanx in advance...

For this kind of setup I would recommend you look a the current HEAD
branch.  It's 'winbind default domain' feature allows you to kill
off
the DOMAIN+ prefix.  It also features some pam_winbind sanity - which
makes it *much* easier to debug what the heck is going on.
