how does the AP Authentication feature in autonomous Cisco APs work ? In the SSID Manager you can select a defined AP Authentication credential. And I created exactly the same username/password on the Radius Server. But where can I define that it's mandatory for all APs to authenticate to the network via Radius ? Even if I enter a wrong password in the AP Authentication section the AP still is accepted by the Radius Server and can serve WiFi-Clients in the same SSID. Any help is greatly appreciated. Thanks.
