[Samba] Two Locations, One Domain - LDAP Auth Failure

>does wbinfo -u show up the user?

No, it doesnt:

[root at alpha ~]# wbinfo -u
Error looking up domain users

And if I try to look at what groups exist:

[root at alpha ~]# wbinfo -g
BUILTIN\administrators
BUILTIN\account operators
BUILTIN\print operators
BUILTIN\backup operators
BUILTIN\replicators

Which is odd, because surely "domain users" (or "authenticated users") should be there too? (I assume it's one of those groups which 'wbinfo -u' is trying to 
list?) But "Domain Users" must exist exist somewhere as 'andy' is part of that group:

[root at alpha ~]# cd /home
[root at alpha home]# ls -ltr
drwx------   3 andy   Domain Users  4096 Sep 19 13:57 andy
[root at alpha home]# su andy
[andy at alpha home]$ id
uid=1002(andy) gid=513(Domain Users) groups=513(Domain Users) context=user_u:system_r:unconfined_t

Any ideas?

Thanks again,

Andy
