wpa supplicat in credentials get cached
Fri May 4 16:55:33 PDT 2012
wpa_supplicant does PMKSA caching. Unless you use a recent wpa_supplicant
(which flushed the PMKSA cache when network blocks are removed), and have a
connection manager that removes networks blocks when you disconnect /
change credentials, wpa_supplicant will used it's cached credentials
instead of re-doing authentication from scratch each time you connect to an
802.1x network. The effect is as you described: the RADIUS server is not
involved in PMKSA-cache-based authentication.
