From the readme
Pressbooks CAS Single Sign-On
CAS Single Sign-On integration for Pressbooks.
Description
Plugin to integrate Pressbooks with Central AuthenticationService (CAS) single sign-on architectures.
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 usermeta 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 usermeta 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
Or, download the latest version from the releases page and unzip it into your WordPress plugin directory: https://github.com/pressbooks/pressbooks-cas-sso/releases
