[Samba] Using SAMBA as a BDC

[Leon]

I am trying to setup SAMBA 2.2.7 on a RH8 box.  Ideally I want it to be a 
backup domain controller. But I continue to get :
smbd/password.c:domain_client_validate(1556)  domain_client_validate: could 
not fetch trust account password for domain IWA : 2 Time(s)

I can look at the server from My PDC (winNT 4.0)

I'm not sure where else to look......
