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.
Thanks and Regards,
SaN
