Configure session idle session timeout in Identity Governance (IG).
Identity Governance 14.4.x
To configure session idle session timeout using IG Management Console, login as AD1\EAdmin user and go to Administration >> Settings >> Property Settings and add session.timeout.minutes property (click the [Add New] button at the bottom) and set the value. By default, the property does not exist in the system.
A change in the session timeout value will be applicable to all the newly created user sessions. You may want to restart IG to reflect the setting immediately.
