Sun Java System Access Manager 7.1 Administration Reference

Maximum Idle Time

This attribute accepts a value (in minutes) equal to the maximum amount of time without activity before a session expires and the user must reauthenticate to regain access. A value of 1 or higher will be accepted. The default value is 30. (To balance the requirements of security and convenience, consider setting the Max Session Time interval to a higher value and setting the Max Idle Time interval to a relatively low value.)
