This attribute accepts a value in minutes to express the maximum time before the session expires and the user must reauthenticate to regain access. A value of 1 or higher will be accepted. The default value is 120. Max Session Time limits the validity of the session. It does not get extended beyond the configured value.
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.
