Authentication is performed on the SMS
               			server using Certificate Authority (CA) certificates and one or more ActivClient
               smart
               			card readers. If there are multiple card readers with multiple cards inserted,
               a dialog
               			box is displayed that enables you to select between card readers when you attempt
               to log
               			in (Menu > File > Login) or during session unlocks. Users are
               			then validated against their Active Directory accounts. The SMS matches a user's
               group
               			in Active Directory with a group on the SMS to determine the user's privileges.

                  				the SMS is in CAC Authentication mode, all SMS users must log in using CAC. No
