Hello,
I have configured NPS on a server (OS: Windows Server 2008 R2) with Active Directory. On the router there's a setting where the RADIUS requests will be forwarded to an external RADIUS server (XAUTH).
In NPS I configured a network policy for VPN connections, chose VPN and a group from Active Directory as conditions and EAP/MS-CHAP-v2 as authentification methods.
Trying to establish a VPN connection, the VPN client asked me for username and password. I entered them and nevertheless I got an error message that both are wrong. Without XAUTH the VPN connection works fine.
Is there a special setting I forgot and have to set?
