Hi
I am trying to get Duo 2FA working on my NPS server which handles user certificate authentication from our VPN which is a windows client connecting into a Fortigate.
There doesnt seem to be a way to make this work. So far I have NPS working and authenticating correctly with user certificates. I just need to somehow add Duo 2FA into the mix. I already have a Duo Auth Proxy setup which handles RADIUS requests for other bits on our network but it doesnt seem to handle user certificate authentication.
Anyone know how I can make Duo work with certificate authentication from a VPN client?
