UTHSC WPCAS

This plugin was developed for UTHSC because there weren’t any existing plugins, being actively maintained, that took full advantage of CAS. SSL certificates are expensive and CAS single sign on prevents the need for multiple certs and provides users with a familiar login experience. We realized the WordPress community needed a go-to CAS plugin so this is a starting point.

phpCAS is the standard, vetted, php library for CAS, so rewriting it from scratch would be counterproductive. It also makes the plugin easier to configure.

This should work with CAS 3.4 and later. It’s possible that it will work with earlier versions but we haven’t tried.

We’ve tested the plugin with and without multisite and it works great either way.

The plugin comes with all settings prepopulated with defaults for UTHSC. Chances are, if you’ve downloaded this plugin you’re already using CAS and hopefully phpCAS so most of these settings should look pretty familiar. If you’re having trouble, check the phpCAS documentation or let us know in the support section.

You may want to test CAS outside of WordPress first to make sure everything works and you’re getting attributes back. For more information about testing and to download some example files from phpCAS, go to https://github.com/uthsc/UTHSC-WPCAS/tree/master/test

If you aren’t getting attributes back, you’ll probably need to make some adjustments to your CAS server. Check the CAS documentation at https://wiki.jasig.org/display/casum/attributes for more information about attributes and getting them to work.

If you are getting attributes back and they are being applied to new user accounts incorrectly, it’s probably just a matter of how the CAS response is being parsed by the plugin.

Right now, it is based on the response we get but it may be different for other users. You can change the array indexes in the plugin settings if they are different from the defaults but if your response is completely incompatible, let us know and we’ll consider updating the plugin to accept more formats.

We’ll be managing the project through Github and would love your feedback. UTHSC WPCAS was developed to work with UTHSC’s configuration but we want it to work for as many people as possible; If you have ideas for features or improvements, let us know or submit a pull request.
