Configuring SSH To Use Freeradius And WiKID For Two-Factor Authentication

In this example, I am installing Freeradius on Fedora Core 7 and running the 3.0RC2 rpms of WiKID on Centos5 (however, the same instructions will work for the 2.0 version of WiKID.) We'll be testing with SSH, however, the same setup should work for Apache, WebDAV, OpenVPN, and any other application that supports PAM.
