Configuring Local EAP
Note The LDAP backend database supports these local EAP methods: EAP-TLS, EAP-FAST/GTC, and
PEAPv1/GTC. LEAP, EAP-FAST/MSCHAPv2, and PEAPv0/MSCHAPv2 are also supported but only
if the LDAP server is set up to return a clear-text password. For example, Microsoft Active Directory is
not supported because it does not return a clear-text password. If the LDAP server cannot be configured
to return a clear-text password, LEAP, EAP-FAST/MSCHAPv2, and PEAPv0/MSCHAPv2 are not
supported.
Note If any RADIUS servers are configured on the controller, the controller tries to authenticate the wireless
clients using the RADIUS servers first. Local EAP is attempted only if no RADIUS servers are found,
either because the RADIUS servers timed out or no RADIUS servers were configured. If four RADIUS
servers are configured, the controller attempts to authenticate the client with the first RADIUS server,
then the second RADIUS server, and then local EAP. If the client attempts to then reauthenticate
manually, the controller tries the third RADIUS server, then the fourth RADIUS server, and then local
EAP. If you never want the controller to try to authenticate clients using an external RADIUS server,
enter these CLI commands in this order:
config wlan disable wlan_id
config wlan radius_server auth disable wlan_id
config wlan enable wlan_id
