Setup RADIUS server using AIS and Cisco AP 1200 series

Ok I have done a significant amount of reading on this issue. All of the documentation found was lenient towards a domain scenario. I am in the process of setting up a RADIUS server for authentication on my network. Though I am in a Domain based network, the machines I wish to authenticate through my WLAN are not par of my domain, neither do I want to make them part of my domain. I have gone through step-by-step configurations and already have the Spa setup IAS setup and certificate installed on both server and client machines. Thing is I just do not seem to be able to get the clients to authenticate using the RADIUS server. Been at this for some days now. I would really appreciate some insight.
