[Samba] "pdb_init_sam failed" fustration

[Barry McClure]

I have a samba server joined into an ADS domain. the join was
successful, however, when i try to attach to a share or the box from an
xp machine in the same domain it prompts me for credentials, and fails
on the correct credentials.

here's the log output:

<snip>

bmcclure at bwmUbuntu:/var/log/samba$ wbinfo -t
checking the trust secret via RPC calls succeeded

wbinfo -g and wbinfo -u are both successful.

getent passwd and getent group are both successful.

using smbclient to attach to a server with -k option is successful.

Not sure what I've done wrong in the config, but I've done it
incorrectly on 2 machines now... running different versions of samba..
3.0.14a and 3.0.21b.

Any help would greatly be appreciated.
