Radius Server with Active Directory

I have an XSERVE with 10.6.7. It is an OD Master that is also bound to Active Directory.

I am trying to set up the RADIUS service to provide authentication to users on the wireless network.

So far, I have been able to set it up to the point where the wireless access point is attempting to authenticate to the server. The client is asked for user ID and password. I will even see the self-signed certificate on the client. However, I am never able to connect to the wireless system.

I tried using an Air Port Express with all the automatic settings from the server, and got the same results.

I tried authenticating with a local OD test user, and that did not work, either.

When I tried it on my network at home (no Active Directory), the RADIUS server worked exactly as expected.

Is there some other setting that must be modified to make this work with AD?
