OK, AD uses what is known as back-links, that is you create something 
and two attributes are created and they sort of point at each other, for 
instance when you add a user to a group, the user gets a 'memberOf' 
attribute that contains the groups DN and the group gets a 'member' 
attribute that contains the users DN.

I think you need to use an existing group (which isn't Domain Users) or 
create a new one and use that groups DN in the 'extended query'
