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 implements a variety of <a href="https://wp-cli.org" rel="nofollow ugc">WP-CLI</a> commands. All commands are grouped into the <code>wp saml-auth</code> namespace.

Since this plugin extends the Shibboleth plugin, you must first have the Shibboleth plugin, available from https://wordpress.org/extend/plugins/shibboleth/ 
installed and activated. Otherwise, the plugin will fail to activate as the shibboleth_user_role filter hook will not be registered.
To use this plugin, you must already have the following setup on your server: 
1. The above Shibbleth plugin. 
2. A UFAD group created for each of the WordPress roles (administrator, editor, author, contributor, and subscriber).
