[Samba] Granting Root privileges to Domain Member Server

[ned.yetley at gsa.gov]

I have the following setup:

2000 Active Directory Forest/Domain (no 2003 DC's yet)
Fedora Core3
Samba 3.0.10

I have successfully joined the AD domain as a Domain Member Server and
can Logon to Fedora with an AD userid and password.

I have been trying for sometime to determine how I can grant an AD group 
and/or AD user
root privileges on the samba member server. Can someone please enlighten 
me as
to how this could be done.
