No if the NAS sends "STOP-without-previous-START" records for
authentication/authorization errors. Your code can free the IP address when this
"STOP-without-previous-START" record arrives. There are many NAS with this
behaviour.
For Cisco users: it was introduced as default in 12.0( < 6 )T. In 12.0( => 6 )T
the default is to not send the stop record, but it's posible to configure it
with "aaa accounting stop-record authentication failure".
I think to remember that the 3com NAS that your are using has this behaviour.
