Unifi Radius MAC-Authentification

Configure a new wireless network (settings > wireless networks) of type WPA personal and configure a security key (shared by all users). In the same window under "advanced options" enable "Radius MAC authentication", select your radius server profile (or create a new) and MAC address format. When a user connects, a radius access request is sent with user and password set to the mac address of the client station (in the format defined before). The radius access accept message can e.g. specify a dynamic vlan so this feature offers more than just a centralised mac whitelist. The wifi key configured in unifi needs to be provided when connecting to the ssid. The radius verification takes place before the key is used but is not sufficient to provide access: a radius access accept is needed as well as the correct key.
