WLC RADIUS server only works if passwords are sent in Clear-text from LDAP.
after authentication - the client & radius server cache session keys for a configurable amount of time
uses TLS to secure other eap methods like certs - user/pass - smart cards. Identifies itself to client with certificate. Utilizes: fast reconnect (faster roaming w/ key caching) and server authentication
