From the readme

Pressbooks SAML2 Single Sign-On SAML2 Single Sign-On integration for Pressbooks. Description Plugin to integrate Pressbooks with a SAML2 single sign-on service. (Shibboleth, Microsoft ADFS, Google Apps, Etc.) Users who attempt to login to Pressbooks are redirected to a Shibboleth or SAML2 Identity Provider. After the user’s credentials are verified, they are redirected back to the Pressbooks network. If we match a Pressbooks user by UID ( 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 user does not have an account in Pressbooks, a new user can be created, or access can be refused, depending on the configuration. Limitations: This plugin does not enable authentication with multilateral Shibboleth. For use in a non-federated, bilateral configuration, with a single IdP. Installation Or, download the latest version from the releases page and unzip it into your WordPress plugin directory: https://github.com/pressbooks/pressbooks-saml-sso/releases Then, create the necessary certificates: Then, activate and configure
