The max connections option would not prevent the same user from
connecting multiple times - it allows for the maximum number of
connections _to a particular service_. If the student is connecting to
his home, then this will work - but the student could be connecting from
lots of places to a different share for which he has permissions, at
which point setting max connections will disable anyone else from
connecting once the number of connections is exceeded.
