I reviewed RFC and FAQ, but i can't fined sane info about configuration of freeRADIUS server (on Windows) to send access-challenge message on access-request. My configuration is (users.conf): test Auth-Type := Local, User-Password == "test" Service-Type = Login-User, Login-IP-Host = 192.99.98.119, Login-Service = Telnet, CS_Priv_Level = 2, Reply-Message = "Hello, %u. Wellcome from RADIUS. You are Administrator" For such configuration RADIUS server (receive access-request)checks Login + Pass and if they are correct sends "Reply-Message" with right "CS_Priv_Level" for Client (access-accept). But i need to validate one more parameter from client and sent for him access-challenge, and i don't know how to configure my RADIUS server to send "Access-challenge". Guys pls help me with the answer or if it's possible give me some link or manual in which i can fined the answer. -- View this message in context: http://freeradius.1045715.n5.nabble.com/Help-me-with-Access-Challenge-config...
