[Samba] wbinfo -g delay

[Garbellotto Vittorio]

Hi,
I have a problem retriving domain groups.
I use SAMBA 3.0.20b and the client is joined to a windows 2003 server
enterprise edition (active directory in 2003 native mode).
I have to wait more than a minute waiting winbind get me domain groups
list. getent group have the same problem.
It seems like winbind is trying to connect to same LDAP server (there is
not).
Any suggestions?
Thanks
Vittorio
