I have a Cisco 2106 wireless controller and trying to install a ACS to autheticate wireless users using Active Directory. I have added the wireless controller to the device groups and set the identity store to use Active Directory. To the Access Polices tab I have added the Radius Access Service. The selection rules tab has a RADIUS Request Attributes with a Dictionary and attribute field, do I need to assign this for wireless clients to authenticate to AD? I have also added the Wireless Controller to the assigned device groups.
