WinNT clients can't see groups on Samba PDC

[,,,]

Hi all,

We have Samba 2.0.7 installed on Debinan/GNU Linux as PDC for Win9x and WinNT
clients. Clients can login to Samba controlled domain.

WinNT can see all user's defined on Samba PDC, but can't use group from
/etc/group. Man page for smb.conf doesn't describe related parameters
(like "domain group map").

How can I solve this problem ?

Best regards,
