samba - Apr 2006 - Join Active Directory, Share: Only allow an AD group read/write?

I've seen a couple of howtos on how to join a a samba server to windows
active directory, so I don't think that will be a problem. But I want to set
up a samba share that only allows read/write access to a group located in active
directory, is that possible?

 

The AD is windows server 2003 by the way...

 

Thanks...
