Finale Cut Server in an Active Directory environment

Dear Friends, Has anybody gotten Finale Cut Server working in an Active Directory environment. We got the server running on a Xserv and bound it to our AD domain. Right now FCS can see local users but can not see AD users/groups. We have tried two approch: 1.) Add AD groups into local groups and then add the to FCS. 2.) Add the AD groups right into FCS using the preferences panel. Neither seems to work. I can still see users on the server but not the AD domain using FCS. Has anybody done this? It seems possible but need guidance. Thanks!
