Modify the Default Inactivity Timeout
You must have Administrator permission to change the default inactivity timeout interval for the group.
By default, users are logged out after a specified amount of time with no activity. You can change the default inactivity timeout value up to a maximum of 720 minutes (12 hours). The initial default value is 30 minutes.
Caution:
Before you change the default inactivity timeout interval, consider
all security issues.
