Description
Smart card authentication must be enforced. The use of smart card credentials facilitates standardization and reduces the risk of unauthorized access. When enforceSmartCard is set to "true", the smart card must be used for logon, authorization, and unlocking the screen saver. CAUTION: enforceSmartCard will apply to the whole system. No users will be able to log on with their password unless the profile is removed or a user is exempt from smart card enforcement. Note: enforceSmartcard requires allowSmartcard to be set to true in order to work. Satisfies: SRG-OS-000067-GPOS-00035,SRG-OS-000105-GPOS-00052,SRG-OS-000106-GPOS-00053,SRG-OS-000107-GPOS-00054,SRG-OS-000108-GPOS-00055,SRG-OS-000112-GPOS-00057,SRG-OS-000375-GPOS-00160,SRG-OS-000376-GPOS-00161
