samba - Jan 2004 - Winbind Problem ("Authentication service cannot retrieve authentication info.")

Hi,

I am using Samba 3.0.1 / Debian Sid. I got winbind to work (Win2k3 ADS
environment) up to a point. I can list users and groups with "wbinfo
-u"
and "getent passwd" works as well. I added "auth sufficient
pam_winbind.so" to /etc/pam.d/login. When I try to login into an ADS
account, access is denied with this message

"Authentication service cannot retrieve authentication info."

Any comments would be very welcome. I followed the instructions of the
samba documentation, but found nothing which would help me in this case.

Thanks in advance.

Regards,
Rainer
