Dear All, I've been trying to autheticate a Wireless Acess Point through a Radius Server for last 1 month, but things doesn't seem to be working for me. The Radius Server is authenticating when I test it with the radtest command. It also worked for a Cisco 2950 switch. But no luck when I use the Access Point. I have tried 3 different accesspoints, including Linksys, D-Link and the Firepro, but none of them worked. I do not get any error when I check the radius in debug mode. It says "Sending Access-Challange to ....", but the client doesn't get authenticated. I seriously need help on this. 1. Do I really need certificates for authentication? Is there a way to achieve WPA with UserName and Password, without installing certificates? 2. Should the AP send "User-Password" attribute to the Radius Server? Or should the Radius Server send an Access-Challange to the AP, and AP does matching and all. Can somebody help me with a working solution of freeradius with AP? Following are the configurations files and the output I am getting while testing. Would appreciate quick response from someone.
