I have seen this problems a few time. I setup a Fedora Core 4 - Freeradius server with apache and when I try to login to the webserver it hangs the webserver. Note in this case the web server and Freeradius are on the same server. But I have also seen it where the web server and freeradius are on two different systems and the web server hangs. I have gotten it to work in the past by stopping the firewall on the radius server and authenticating and then restarting the firewall. And everything works for some reason. Which really seems strange. I am running Fedora Core Linux for the web servers. And Redhat ES4 Linux for the radius servers.
