TL;DR

AI summary of the plugin's readme

wpCAS is for WordPress administrators who need to integrate their site into an existing CAS (Central Authentication Service) single sign-on environment. It solves the problem of centralizing user authentication across heterogeneous applications by redirecting WordPress logins to a central CAS server and matching verified CAS usernames to WordPress accounts.

Single sign-on via CAS
Redirects login to central CAS server
Matches CAS username to WordPress username
Relies on native WordPress authorization
Refuses access without WordPress account
Admin-defined provisioning function for new users

Frequently Asked Questions

Common questions about wpCAS

I've only tested it with the 1.0 release available from ja-sig.

Users who attempt to login to WordPress are redirected to the central CAS sign-on screen. After the user's credentials are verified, s/he is then redirected back to the WordPress site. If the CAS username matches the WordPress username, the user is recognized as valid and allowed access. If the CAS username does not exist in WordPress, you can define a function that could provision the user in the site.

Each environment is different; each environment probably needs its own solution for this. I've posted my user provisioning script here, if you find something in there that works, leave a comment.

There is none. This looks familiar... You might be thinking of Stephen Schwink's CAS Authentication plugin. This plugin would be a lot different if I couldn't lean on Stephen's excellent work. My primary reasons for branching (under the the terms of the GPL) were that I wanted it to work better with WPMU and needed an easier way to hook-in functions to provision users and wanted to do that while also making it easy to upgrade using SVN (thus the config file).
