If you want to auto logoff a technician/requester after a predefined idle time then this can be achieved by adding an entry in an xml file.
We need to edit the value Session timeout to activate this. Edit the file named session_timeout in the path,
server/default/conf/web.xml
By default the value is set to 6 hours , ie 360 min. And this can be configured based on the requirement.
Save the file and restart the application service for the changes to get applied.
