Hai to all, We are using freeradius 3.0.13 version EAP=PEAP (MSCHAPV2)only in our network .Few day's back we configure the server.At the time mobile devices and windows 10 system are logged through our domain account.After two day's our mobile devices only login happen but windown 10 it is not logged .It is showing some TLS error.i have given the error below.We are not using any certificate(Server,Client) before and now also.i don't why the windows 10 system won't login. We don't want using and PAP or CHAP or MD5.We need only PEAP.If it is must for server certificate for using windows 10?or below windows 7? only required for certificate.Kindly suggest to me to resolve my issue.
