Hello,
My Server 2012 with NPS to authenticate clients for WiFi using RADIUS has started denying requests.
The logs show the last successful auth was on 26th of August.
The event log is full of events that say that the user was denied access because
"The client could not be authenticated because the Extensible Authentication Protocol (EAP) Type cannot be processed by the server."
From what I can see, the successful auth entries in thel og in the past were using the PEAP protocol. But the newer requests are using EAP.
To the best of my knowledge, nothing has changed on my access points configuration or on my server. Devices that worked fine now (smartphones, laptops etc) are now apaprently using the incorrect authentication protocol!
What could make the authentication protocol change in this way? Something in the access point perhaps that's advertising the incorrect protocol?
