Hi ! I'm trying to set up a freeradius (1.1.0) server to proxy ms-chap-v2 to a ms ias server. If I send ms-chap, then the proxy works. But if I send ms-chap-v2 then i get this error message (from debug) : Sending Access-Request of id 1 to 192.168.1.1 port 1812 NAS-Identifier = "vpn.domain.com" NAS-Port = 0 NAS-Port-Type = Virtual Service-Type = Framed-User Framed-Protocol = PPP User-Name = "username" MS-CHAP-Challenge = 0xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx MS-CHAP2-Response = yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy NAS-IP-Address = 192.168.1.10 Proxy-State = 0x3339 Waking up in 3 seconds... rad_recv: Access-Reject packet from host 192.168.1.1:1812, id=1, length=46 Proxy-State = 0x3339 MS-CHAP-Error = "\000E=691 R=0 V=3" Is this possible ? Should it work ? Is it possible to proxy ms-chap-v2 ?
