[Samba] NOT FIXED: Win2003 ADS, wbinfo -u and -g bug

[herman]

System: Win2003 ADS, Samba 3.0.26a on RHEL5.

I thought I had this fixed but sadly no - it came back.  The situation 
changes when I reboot the PC, or cycle power on the PC.  This indicates 
to me that there is a structure in winbind that is not initialized properly.

wbinfo -t: OK, shows domain joined fine.
wbinfo -g: Shows all groups, or only the first two BUILTIN groups, or 
nothing at all.
wbinfo -u: Shows all users, or no users.

Login works if wbinfo -g shows all groups, fails otherwise.

kinit  user at DOMAIN: works
wbinit -a user%domain: works

[root at ggg-mmm-w000048 ~]# wbinfo -t
checking the trust secret via RPC calls succeeded

[root at ggg-mmm-w000048 ~]# wbinfo -g
BUILTIN+administrators
BUILTIN+users

[root at ggg-mmm-w000048 ~]# wbinfo -u
Error looking up domain users

recieve failed (NT_STATUS_LOGON_TYPE_NOT_GRANTED)

Does anyone have any better ideas, or should I get the source code and 
debug it myself?

Cheers,
