smb.conf

hi, 

i found the following issue after trying to integrate a new installation of samba.
i tried already different versions and it seems to be the same on all of them. i already did a new installation of the machine.

if i try to enumerate all users of the ad domain with wbinfo -u it lists all the ad users, also if i try to list them with their mapping, using getent passwd -> works perfectly!

but, on groups, the wbinfo -g works and lists all groups. not the getent group command. it does not list any of the ad groups. if i do an strace getent group, i can see, it is accessing winbind, but no groups are returned.
if i then tty it with an explicit group name (getent group 'domain admins') it gives me the group and mapping correctly. 

i have attached my smb.conf, and a Level 10 set of logfiles.

is there anything i failed to check, or might this be a bug?
