How to set user session expiry

Product Feature: Visual Dialogue
Administrators of Portrait Dialogue (PD) will normally want to ensure that any users who leave their sessions open do not affect other active users of the system.
Within Dialogue Admin, there is a setting called UserSessionExpiry that allows administrators to adjust the time out duration (in minutes) for unused user sessions.

The default time out value is 120 minutes (as in the screen shot). Changing this to a value of zero means that user sessions will never expire.
