Microsoft NPS authentication Problems



we have some iap103 firmware Instant_Pegasus_6.4.2.0- on it.

I want to authenticate one ssid with a ms nps (server 2012r2) against our active directory.

The NPS Server shows the following error:

Reason Code: 21

Reason: An NPS extension dynamic link library (DLL) that is installed on the NPS server rejected the connection request.

what is the problem?

Is the Instant AP known as a RADIUS client in NPS? Are you using the RADIUS proxy feature on the Instant AP? That will source all of the RADIUS requests based on the Virtual Controller IP address.
