SAML authentication for WordPress, using the bundled OneLogin SAML library or optionally installed <a href="https://simplesamlphp.org/" rel="nofollow ugc">SimpleSAMLphp</a>. OneLogin provides a SAML authentication bridge; SimpleSAMLphp provides SAML plus a variety of other authentication mechanisms. This plugin acts as a bridge between WordPress and the authentication library.
If your organization uses Google Apps, <a href="https://pantheon.io/docs/wordpress-google-sso/" rel="nofollow ugc">integrating Google Apps with WP SAML Auth</a> takes just a few steps.
The standard user flow looks like this:
<ul>
<li>User can log in via SAML using a button added to the standard WordPress login view.</li>
<li>When the button is clicked, the user is handed off to the authentication library. With OneLogin, the user is redirected to the SAML identity provider. With SimpleSAMLphp, the user is redirected to the SimpleSAMLphp install.</li>
<li>Once the user is authenticated with the identity provider, they’re redirected back to WordPress and signed in to their account. A new WordPress user will be created if none exists (although this behavior can be disabled).</li>
<li>When the user logs out of WordPress, they are also logged out of the identity provider.</li>
</ul>
A set of configuration options allow you to change the plugin’s default behavior. For instance, <code>permit_wp_login=>false</code> will force all authentication to go through the SAML identity provider, bypassing <code>wp-login.php</code>. Similiarly, <code>auto_provision=>false</code> will disable automatic creation of new WordPress users.
See installation instructions for full configuration details.

This plugin is designed to support integrating your WordPress site into your existing identity management infrastructure using a <a href="https://incommon.org/software/shibboleth/" rel="nofollow ugc">Shibboleth</a> Service Provider.
WordPress can be configured so that all standard login requests will be sent to your configured Shibboleth Identity Provider or Discovery Service. Upon successful authentication, a new WordPress account will be automatically provisioned for the user if one does not already exist. User attributes (username, first name, last name, display name, nickname, and email address) can be synchronized with your enterprise’s system of record each time the user logs into WordPress.
Finally, the user’s role within WordPress can be automatically set (and continually updated) based on any attribute Shibboleth provides. For example, you may decide to give users with an eduPersonAffiliation value of faculty the WordPress role of editor, while the eduPersonAffiliation value of student maps to the WordPress role contributor. Or you may choose to limit access to WordPress altogether using a special eduPersonEntitlement value.

Shibboleth

We had no trouble installing and configuring the plugin. When we ran into an issue, it was no trouble to interact with the plugin authors. 

This plugin just works

Allows WordPress to externalize user authentication and account creation to a Shibboleth Service Provider.
