I've configured NPS on Server 2012 for RADIUS authentication and we're using Central to manage our IAPs. I'm getting Error 6274 with Code 22 "The client could not be authenticated because the Extensible Authentication Protocol (EAP) Type cannot be processed by the server." From research, it appears I need to install a trusted certificate, but I'm not sure the steps needed and if I need to distribute to all RADIUS clients. I've read that public CA certs don't need to be distributed, but private certs do... is that true? Also, is there any way to get around a certificate install using PEAP and MSCHAPv2? Thanks.
