Hi Ain Abdullah!
This functionality will be available in next ITMS 8.6 RU3 release
Quick overview:
1. There will be "Configure Sessions" page where you can enable this functionality and set required settings
2. On "View Sessions" page will be shown all recorded activities.
Symantec Administrator is able to force "Log off" or "Reset" for existing current sessions.

User will see this message in browser when session is expired == auto logged off

If user is not allowed to access SMP Console, then this message will be shown in browser

Best regards,
IP.
