[strongSwan] Any working two-factor authentication with Windows?

[Husy -]

I know that StrongSwan supports multifactor authentication schemes such as RFC4739. I would like to know if there exist any two-factor combination where one of them is RADIUS, either IKEv1 or IKEv2, which works with Windows (Win7 and above) native VPN client . Note that I am not asking about hybrid authentication where server and client are authenticated with different methods. For instance the client is first authenticated with certificates then username password via RADIUS.

Correct me if I am wrong but as of now, Windows still does not support RFC4739. What are our options for multi-factor authentication with Strongswan server and Windows client?

Thanks!
