Earlier today I set up an 802.1X EAP wireless network with a Ruckus WLAN controller.
Here's the setup:
Ruckus WLAN controller with a few dozen headless Ruckus WAPs
Domain CA that has enrolled in AD and is pushing certificates to all client pcs via group policy
Windows 2008R2 NAP server authenticating clients based on AD group "Domain Users"
I set up the NAP server and ruckus according to this guide - http://forums-archive.ruckuswireless.com/forums/8/topics/1278
Everything looked perfect, but I was getting a strange error on my test client when attempting to join the wireless network. Here's the error message:
A request was made to authenticate to a wireless network.

I tore every piece of my NAP setup apart -- went through every line of relevant group policy, certificates, Ruckus wireless configuration, when I found the issue.
I had set the NAP server (Windows 2008R2) to use the certificate of the trusted domain CA to sign the EAP messages. Though the client had the same trusted CA installed locally, a trusted CA is not a certificate, so the client was rejecting the two-way EAP authentication.
The issue was fixed when I changed the certificate the Windows NAP server was using to sign the EAP messages. When I updated it to a certificate signed by the CA (rather than the CA's own certificate), everything started working immediately.
Good luck to you!
