Configuring CAS On Ubuntu For Two-Factor Authentication With WiKID

Single sign-on is a great technology. Requiring users to login to multiple applications is huge hassle, encourages password reuse and simple passwords. Security needs to focus on usability. If you can make a user's life better while increasing security, everybody wins. In this how-to we will set up the open-source CAS SSO product with the WiKID Strong Authentication Server for two-factor authentication for sessions and mutual https authentication for host authentication. Obviously using two-factor authentication for the login increases security because the user must have the factors to get access, in this case, knowledge of the PIN and possession of the private key embedded in the token. The CAS server is running on Ubuntu 11.04 Server and is using Radius to talk to the WiKID Strong Authentication Server Enterprise Edition.
