I work in a college and we have a problem with students locking computers and then not coming back to them. We, as administrators can unlock them, but we need to allow other non technical members of staff to unlock machines. I understand that usually only the user who locked the machine or an administrator is capable of unlocking it. But is there any way of giving a user or group the ability to do so as I cannot give the other staff administrative accounts? I have been looking into this but so far have drawn a blank.
