[Samba] Mapping ADS groups

[Greg Adams]

I've got a Samba 3.0.7 member server of an ADS domain. Is there some
way to map everyone in an ADS group to a single user for the purposes
of Unix permissions? I thought I could do this with an smb.conf entry
of:
usernam map = /opt/samba/etc/username.map

and an entry in the username map of
smbuser = @"DOMAIN\Group Name"

but that doesn't seem to do it. Using a username map entry of
smbuser = "DOMAIN\User ID"
works, but the ADS domain has over 10000 users in the target group I
need to map, and I don't want to elaborate each of those users in the
username map.
