I am trying to configure a remote desktop session to authenticate with a remote RADIUS server. The setup consists of a remote desktop gateway and a remote RADIUS server.
The NPS on the remote desktop gateway has a connection request policy that forwards the connection authentication request to a remote RADIUS server group.
The remote RADIUS server group has the remote RADIUS server IP and shared secret. Realm stripping is also configured to remove the realm name.
The remote RADIUS server logs shows that it was able to receive the forwarded connection authentication requests but the user authentication failed. Using packets capture from Wireshark, it is observed that the User-Password attribute is not found in the RADIUS Access-Request from NPS to the remote RADIUS server.
Is there some configuration that I must have missed out or configured wrongly?
Thank you for your help!
