samba - Sep 2002 - Problem when adding SAMBA-server to a WinDomain

Hello!

We have a Sambaserver which is used in a Windows NT Domain (added with smbpasswd
-j DOMAIN -r SERVER -U USER%PWD)

On the server there is a Sambashare and the users should be autenthicated by the
domainserver. We heve two groups - one with read/execute and one with
read/write/execute permissions.

When we watch the grouplist with the command "wbinfo -g" we can see
the read/write/execute-group .
With the "getent group"-command we can't see this group.

When the user tries to connect to the share we get following error-message in
the /var/log/messages-file:

    "winbind gid range full!"

and the access fails.

Does someone has an idea where the problem coul'd be?
It would be a great help for me?

Thanks in advance and
regards

Martin
