SSTP with EAP?

So, it doesn’t look like anyone responded to my thread about implementing SSTP with NAP, but has anyone gotten EAP working with the SSTP server? I don’t really care what type, I’ll be happy with EAP-MSCHAPv2 or PEAP (eventually want to use smart cards for user certificate based auth), but for now, I’d just like to get an extra layer of security beyond the initial TLS session between my clients and router. I’ve got everything working perfectly from a basic MSCHAPv2 setup using Server 2012r2 AD with NPS. Any help is appreciated. Thanks!
