WordPress.org

1. Download phpCAS and place it on your webserver so that it can be included by the wpCAS plugin.
2. Place the plugin folder in your wp-content/plugins/ directory and activate it.
3. Set any options you want in Settings -> wpCAS or in the wpcas-conf.php file.
4. The plugin starts intercepting authentication attempts as soon as you activate it. Use another browser or another computer to test the configuration.

wpcas-conf.php

wpCAS can be configured either via the settings page in the WordPress dashboard, or via a configuration file. See wpcas-conf-sample.php for an example. If a config file is used, it overrides any settings that might have been made via the settings page and that page is hidden.

Use of wpcas-conf.php is recommended for WordPressMU installations, as doing so hides the settings menu from users.

WordPressMU Installation

1. Download phpCAS and place it on your webserver so that it can be included by the wpCAS plugin.

4. Set the options in the config file.
5. The plugin starts intercepting authentication attempts as soon as you activate it. Use another browser or another computer to test the configuration.
6. Consider creating a function to provision user accounts for CAS-authenticated users who do not have WordPress accounts.
