Thanks,
I have been through these and they don't help my issue. I keep getting this error, An NPS extension dynamic link library (DLL) that is installed on the NPS server rejected the connection request. It happens instantly with no attempt at TFA.

Do you have any FW on Server, so disable and test it.

Thanks, still not finding the problem. I was hoping to find someone that got this working and see if they can divulge what they did. There are some Cisco videos and articles about using and ASA but not so much with the Firepower.

I have not set up one, but ASA and Firepower work in the same way, nothing changed in terms of concept, except Code in ASA vs Firepower.
Sure any community member can chip in here and give suggestion of they had same issue and how they resolved here (happy to learn from their views)

Turns out this article helped get it working, ASA VPN User Authentication against Windows 2008 NPS Server (Active Directory) with RADIUS Configuration Example - Cisco
