Every user can only have one login instance on the system. Sessions with unsuccessful logouts can be terminated by any administrator with user management rights for that user. At "Admin > User > Users" an x will be displayed in the right column for all users who are currently logged in. By clicking this icon you can log out a user and terminate their session.

If a user is logged out by an administrator, a 15 second timer will run out before the actual logout and a corresponding message will be displayed to inform the user.
