Description (partial)

A AP in flexConnect local auth should not send a access-request packet to radius if no username/password. The Radius should send a reject back to the AP but in our case the ACS 4.2 does not. This causes the AP to mark the server as dead.

flexconnect local switching local auth. Radius not configured (or bug) to send back access-reject. If the reject is not sent the AP will mark it as dead.

using leap/peap. very random behaviour - seen 1-2 times a day.

called-station-id is sent in this packet but blank username.
