[Samba] winbind with server 2003

[Simone Stanzani]

I have a RedHat 5.2 and I have some problem with a Windows 2003 Domain.
I have configured winbind (the configuration is the same and works in
other installation) if I use as a password server a Windows 2000 Domain
Server always works, if I use as password server a Windows 2003 Domain
Server it is impossible validate on domain via ssh and I have to to turn
off the Windows 2000 server.
What could be different on server 2003, is the first server 2003 that
does not works ...
With Windows 2003 server i see users and groups with wbinfo command
but if i try to connect via ssh with a domain user this is the output
of /var/log/secure
