SimpleShib is a WordPress plugin to authenticate users with a Shibboleth Single Sign-On infrastructure. This plugin will not work if you do not have a Shibboleth IdP and SP already configured.
When a WordPress login request is received from a user, the Shibboleth session is validated. If the session does not exist, user is redirected to the IdP login page. Once authenticated at the IdP, the user is redirected back to WordPress and logged into their local WordPress account. If a local account does not exist, one can optionally be created.
User data (login, name, and email) is updated in WordPress from the IdP data upon every login. Additionally, the user is restricted from manually changing those fields on their profile page.
On multisite instances of WordPress, SimpleShib can only be network-activated.
The plugin settings include options for autoprovisioning, custom IdP attributes, password reset/change URLs, and session initiation/logout URLs.
SimpleShib is developed on GitHub. Please submit bug reports and contributions on <a href="https://github.com/srguglielmo/SimpleShib" rel="nofollow ugc">the GitHub project page</a>. For general support and questions, please use the <a href="https://wordpress.org/support/plugin/simpleshib/" rel="ugc">WordPress support forum</a>.
This plugin is not affiliated with the Shibboleth or Internet2 organizations.
