Require new login
Set the time when the administrator must log in (again).
Require a new login to the server after an inactive period (minutes)
Management and Security Server times out when a user has not launched a session or otherwise interacted with the MSS Administrative Server during the specified time. The user must log in again to open a new host session or access the MSS Administrative Console. Host sessions that are already open are not affected.
When you are configuring sessions and settings, you may want to lengthen the timeout period to avoid disruption. Then, reset the time when you’re done.
Require new login for each host session launched by a user
When LDAP authentication is in effect, you can require users to log in to the MSS Administrative Server each time they launch a session. This option does not apply when the user is logged in as administrator.
