User never get disconnected (was Re: Simultaneous-Use problem)

[tnt at kalik.co.yu]

If you are happy with reliability then fix checkrad and it will clean
these random drops. That is the utility that radiusd calls to check
stale entries and in sql.conf you can enable deletion of such entries.
Just make sure that such users are not listed as active by the hotspot.
If NAS thinks they are still loged on, RADIUS can't do anything about
it.
