I'm trying to set up RADIUS authentication with our company domain on my office's wireless network. I've got IAS installed on the domain controller, and the wireless access point is registered as a client of the IAS service. I can see from the IAS logs that my attempts to authenticate with my domain account are getting passed-through by the wireless access point, but for some reason it never authenticates. It's like it isn't getting a response. It just sits there waiting until the operation times out. There's no firewall on the domain controller, so I don't need to worry about opening ports. The router isn't blocking traffic on the RADIUS ports either, because then the authentication requests wouldn't be reaching the domain controller in the first place. All of the user accounts are set to allow dial-up connections, which is apparently required for IAS to approve authentication requests, but it's still damn well not doing it. Anybody have any ideas what I might be missing?
