Hi all,
Im trying to configure wireless client authentication in wing controller with microsoft NPS.
I searched alot but i dont seem to find any document explaining that, so i just went on with my previous knowledge and configured the ssid authentication in wing to use EAP and did the necessary configuration in NPS but i get the error : "the client could not be authenticated because the extensible authentication protocol (eap) type cannot be processed by the server. extreme networks".
Any help ?
Thanks.

Can you check the event-history on the AP and see what reason codes you are getting from the NPS server.
I am going to assume you will see rejects. If this is the case, you will need to resolve this from the NPS side.

If you are seeing server timeout confirm if the AAA policy is configured for the controller to be the radius proxy and that the controller is added as a radius client.

To troubleshoot further you can use the articles below to collect additional data.
