Answer: probably not.
>From what I've read, supplicants can send an EAPOL-Logoff message to
an authenticator (ie. an AP/switch). The authenticator could then
disable the "port." I can't think of any good reason the authenticator
would send this message to RADIUS. I've also read that Windows clients
will send an EAPOL-Start message when a user logs off instead of an
EAPOL-Logoff. Neither of these are really good methods for determining
whether an association between a client and an AP is lost.
