samba - Dec 2004 - group policies in samba PDC for windows 2000 professional and xp clients

I have configured a samba PDC with windows 2000 professional and xp clients
and the PDC working fine, but how can i implement group policies for clients?
like i want to disable run command from start menu or i want to allow
a group to use msn and other groups shouldn't able to use msn.
how can i implement these group policies object in samba PDC?

I don't believe there is any way to create group policies on SAMBA domain
controllers.

However, you can make NT4 style domain policies.  Use "poledit" from
the
WindowsNT resource kit to create your policies.  Save the policy as
ntconfig.pol in the netlogon share.  These policies will work with
Windows2000 and XP.
