advice wanted on pam with winbind

[Mark Cooke <mark mmebs co uk>]

Iam trying (being the operative word to setup winbind to authenticiate my 
linux box against a NT PDC, which out much sucess so far).

It looks like the problem could be to do with the pam setup.
Iam curently running samba-2.2.2-8 and pam-0.75-18.7 on RH 7.1.

Iam not sure what exactually to enter in the fileds to enable the winbindd 
to use pam correctly.

from the winbind FAQ, it states the following:

In /etc/pam.d/* replace the auth lines with something like this:

auth       required     /lib/security/pam_securetty.so
auth       required     /lib/security/pam_nologin.so
auth       sufficient   /lib/security/pam_winbind.so
auth       required     /lib/security/pam_pwdb.so use_first_pass shadow nullok


Note in particular the use of the sufficient keyword and the use_first_pass 
keyword.

Now replace the account lines with this:

account required /lib/security/pam_winbind.so

and Ive tried this and I don't think its working correctly, could anyone 
possably help he out or advice me what would/should go where.

Thanks in advance
