I have build this simple script that will take the current console user of a machine then pull their information from AD and add it into JSS.

I have this run once a week, this way JSS will have the most up to date information on who is using the machine. For example if the machine moves to a different person in the office and no one tells IT, because no one ever does that, then you will see in JSS who was using it in the last week.
