I have an IIS box running in our DMZ and we want to try to create a single sign on experience for our users. I want to use radius and I have it set up and the firewall ports are open, but IIS doesn't seem to be using radius. All non-local users (server is not part of AD of course) are not authenticated. I have searched here, other techie sites and google, but very little info on this. There is a company called www.tcpdata.com
that has an isapi filter that does this, but it seems that this should be available using MS SW.
