[Samba] domain groups and winbind

[Collen]

Well must i got the following prob,

i got samba and winbind up and running..
but when i want to alter the file and directory permissions on a samba
share,
there are only domain users, i miss the domain groups!
the server uses winbind to do that..
with wbinfo and getent the users and groups names are resolved..
so winbind must be working correct.. ??
but still no groups in my domain list at the winbind/samba server..
anny cluess ??!
