[Samba] 2.2.7 to 3.3.12 upgrade issue

Upgraded an AIX Server from AIX 5.3 TL3 with Samba 2.2.7 to AIX 7.1 TL3 
with 3.3.12. Client uses AD authentication.
Upgrade did not change smb.passwd or smb.conf.

Windows users trying to mount a share are presented a request for their 
credentials; whether they supply the AD or AIX credentials, the access 
is denied - "Logon failure: unknown user name or bad password." The smbd 
and nmbd processes start without error. I presume that as the server was 
working, it is already registered in the domain. I would not expect the 
OS version change to affect that registration.

With AD authentication, I would presume that I need to capture something 
on the AD side to see what's happening? But I don't envision that the AD 
just blesses the credentials and opens a link to the server.

What will help me identify the problem?
