We would very much like to know if anyone has successfully got FreeRadius to work with a Cisco 2106 WLAN controller. We have attempted to make it work, but the clients get stuck on "validating user." You can see this occur in the FreeRadius debugging. It first looks for a certificate and then even tries to pull the Active Directory user name. We would really love to see the controller work with FreeRadius.
Thanks for your help everyone!
