RADIUS Authenticated SSID

OpenWiFi 2.0

When authenticating clients with back office RADIUS systems, the configuration of OpenWiFi permits this on a per SSID basis.

Many parameters are possible with RADIUS authentications given the many methods in use worldwide. Many of the EAP methods have configuration options described below.
