AD4Unix & Samba-3.0.20b+winbind

Scenario:  Samba-3.0.20b domain member server on SuSE 9.3 (w/ all 
available patches applied) providing kerberos authentication through a 
Windows 2000 domain with AD4Unix services installed.

1. Can only view users from one OU in Active Directory (default is: 
CN=Users, problem container is: OU=authenticated)
2. According to log.winbind and log.smbd authentication fails with 
error:   check_ntlm_password:  Authentication for user [testj] -> 
[testj] FAILED with error NT_STATUS_WRONG_PASSWORD.  Is this error due 
to falling back to NTLM authentication vs. Kerberos TGT systems?

Troubleshooting performed:
1. Used 'net ads leave' to remove from domain, updated Samba+Winbind 
from 3.0.13 to 3.0.20b
2. Manually removed machine trust account from active directory
3. Manually removed cache files for Samba prior to upgrade
4. Attempted using 3.0.21rc1 release with same results
5. Created a Win 2K test domain w/o AD4Unix and Samba-3.0.13 ADS member 
server which would authenticate via Kerberos without problems.
6. Upgraded Samba to 3.0.20b and still worked fine on test domain w/o 
AD4Unix setup
7. Am in the process of upgrading Win2K domain server (in test env.) to 
provide AD4Unix services to see if it breaks.

Any help, insight into this is definately appreciated
