Users who attempt to login to Pressbooks are redirected to the central CAS sign-on screen. After the user’s credentials are verified, they are redirected back to the Pressbooks network. If we match a Pressbooks user by CAS username (stored in user\_meta table), the user is recognized as valid and allowed access. If no match, then try to match a Pressbooks user by email (and store a successful match in user\_meta table for next time). If the CAS user does not have an account in Pressbooks, a new user can be created, or access can be refused, depending on the configuration. Installation ------------ [](#installation) ``` composer require pressbooks/pressbooks-cas-sso ``` Or, download the latest version from the releases page and unzip it into your WordPress plugin directory: Then, activate and configure the plugin at the Network level. Read the integrations documentation for more info: ### Security Considerations [](#security-considerations) Set the `PB_CAS_CERT_PATH` environment variable to configure validation of the CAS server. Used by `CURLOPT_CAINFO` for peer and host verification: ``` putenv( 'PB_CAS_CERT_PATH=/path/to/cachain.pem' ); // Path to the CA chain that issued the CAS server certificate ``` ### Advanced Configuration [](#advanced-configuration) The email can be filtered, example: `add_filter( 'pb_integrations_multidomain_email', function( $email, $uid, $plugin ) { /* Custom use case, return $email */ }, 10, 3 );` Because this plugin uses the fabulous [apereo/phpCAS](https://github.com/apereo/phpCAS) library, [many other configuration variables can be tweaked](https://github.com/apereo/phpCAS/tree/master/docs/examples).
