Alternate interpretation:

Your security systems correctly notice a logon from Zanzibar or similar
remote location, to a userid that properly should logon only from campus.

Your security system totally fails to flag a Bad Guy(TM) who logs onto
such a userid from on campus, after they snag the password from the Post-It
or shoulder-surfing.

Quick test - if a userid logged on from a location 3 cubicles over from the
user's assigned offfice area, would you notice/flag it?
