       When using freeradius with wpa_supplicant I have noticed freeradius does not bump the EAP id when sending back the Access-Accept packet. wpa_supplicant notices this and has a work around. Will the WPA drop this packet (it is important because it has the keys in the attributes). Has anyone reported this bug?    The reason I ask is because after receiving the accept packet, wpa_supplicant goes into AUTHENTICATED state but cannot connect to the network, or associate. Any ideas?
