[Samba] allow samba domain group RDP access

[Evan Ingram]

I want to allow RDP connections to a Win2008 server which is joined to a 
samba domain.

I've added a samba group that my user is a part of to the Remote Desktop 
Users members, but it doesnt seem to work. Still says to log on to this 
computer you must be granted the allow log on through terminal services 
right.

If i specifically add the samba user to the Remote Desktop Users group i 
get the specified domain either does not exist or could not be contacted 
when i try and log in.

any ideas?
