Well.. When used without WPA, it allows one more way of kicking a
station off the network (i.e., DoS) by sending EAPOL-Logoff. However,
this is not really anything new, since the same thing can be done
sending a spoofed IEEE 802.11 deauthentication frame. IEEE 802.1X
authentication itself is fine, assuming the EAP method is selected
properly, i.e., use something with tunneled encryption, e.g., EAP-PEAP
or EAP-TTLS; or EAP-TLS if you have infrastructure for client
certificates.
