Authorizer restricts access to a WordPress site to specific users, typically students enrolled in a university course. It maintains a list of approved users that you can edit to determine who has access. It also replaces the default WordPress login/authorization system with one relying on an external server, such as Google, CAS, LDAP, or an OAuth2 provider. Finally, Authorizer lets you limit invalid login attempts to prevent bots from compromising your users’ accounts.
View or contribute to the plugin source on GitHub: <a href="https://github.com/uhm-coe/authorizer" rel="nofollow ugc">https://github.com/uhm-coe/authorizer</a>
Authorizer requires the following:
<ul>
<li>CAS server (2.x, 3.x, 4.x, 5.x, 6.x, or 7.x) or LDAP server (plugin needs the URL)</li>
<li>PHP extensions: php-ldap, php-curl, php-dom</li>
</ul>
Authorizer provides the following options:
<ul>
<li>Authentication: WordPress accounts; Google accounts; CAS accounts; LDAP accounts; OAuth2 accounts</li>
<li>Login Access: All authenticated users (all local and all external can log in); Only specific users (all local and approved external users can log in)</li>
<li>View Access: Everyone (open access); Only logged in users</li>
<li>Limit Login Attempts: Progressively increase the amount of time required between invalid login attempts.</li>
<li>Shortcode: Use the <code>[authorizer_login_form]</code> shortcode to embed a wp_login_form() outside of wp-login.php.</li>
</ul>

Authorizer

Integrates nicely with Google hosted domain/s. Couldn't be happier with how it works!

Integrates well with Google Logins

I've experimented this plugin on a multisite and everything works pretty well.

Works great even on a multisite setup

Authorizer limits login attempts, restricts access to specific users, and authenticates against external sources (OAuth2, Google, LDAP, or CAS).

If you’re happy with this plugin : 
As a reward for my efforts, I would like to receive T-shirts (or other goodies) as gifts from the universities or companies that use it. 
My size is L. Best regards.
This Apereo CAS authentication plugin has no phpCas library dependency. This is not only an authentication plugin. 
You can build custom authorization rules according to cas user attributes populated. If user don’t exist in WordPress 
database, it can be created automatically. There are many features. You can customize everything.
<h4>Website</h4>

<h4>Development and release environment</h4>
This plugin is now developed and tested from a github repository. You can find it here : 
https://github.com/WP-Cassify/wp-cassify-develop
Don’t hesitate to contribute to this project. You can fork it and make pull requests !
<h4>Requirements</h4>
<ul>
<li>Require at least PHP version 7.0</li>
<li>Require at least PHP CURL package</li>
</ul>
<h4>Features included</h4>
<ul>
<li>SLO (Single Log Out) support (thanks to dedotombo and me)</li>
<li>Adding NCONTAINS operator (thanks to blandman)</li>
<li>Fix bug on Gateway mode (autologin) (thanks to dedotombo again). Now it’s now necessary to hack theme files to fire it.</li>
<li>Adding option logout on authentication failure to not disturb users</li>
<li>Initialize PHP session at a later stage (on wp_loaded not on init)</li>
<li>
Adding some customs hooks and filters.
</li>
<li>
Tested with Apereo CAS Server version 7.2.5
</li>
<li>Compatible with CAS Protocol version 2 and 3</li>
<li>Automatic user creation if not exist in WordPress database.</li>
<li>Synchronize WordPress User metas with CAS User attributes.</li>
<li>Add support for multivaluate cas user fields. Now multivaluate fields can be serialized to be stored in custom WP User meta.</li>
<li>Backup / Restore plugin configuration options settings</li>
<li>You can choose CAS User attributes you want to populate. Then you can access them via PHP Session.</li>
<li>
Be careful, to access to CAS User Attributes from your theme file (from 1.8.4), use code below :
<pre><code><?php
 if ( isset($GLOBALS['wp-cassify']) ) {
 print_r( $GLOBALS['wp-cassify']->wp_cassify_get_cas_user_datas() );
 }
?>
</code></pre>
</li>
<li>
Set up WordPress Roles to User according to CAS User attributes.
</li>
<li>If plugin is network activated, you can define User Role Rule scope by blog id.</li>
<li>Authorization rule editor.</li>
<li>Compatible with WordPress Access Control Plugin.</li>
<li>Manage URL White List to bypass CAS Authentication on certain pages.</li>
<li>
Much simpler bypass authentication with post method provided by Susan Boland (See online documentation). Create wordpress authentication form with redirect attribute like this :
<pre><code><?php

 $args = array(
 'echo' => true,
 'remember' => true,
 'redirect' => site_url( '/?wp_cassify_bypass=bypass' ),
 'form_id' => 'loginform',
 'id_username' => 'user_login',
 'id_password' => 'user_pass',
 'id_remember' => 'rememberme',
 'id_submit' => 'wp-submit',
 'label_username' => __( 'Username' ),
 'label_password' => __( 'Password' ),
 'label_remember' => __( 'Remember Me' ),
 'label_log_in' => __( 'Log In' ),
 'value_username' => '',
 'value_remember' => false
 );

 wp_login_form( $args ); 
?>
</code></pre>
</li>
<li>
Receive email notifications when trigger is fired (after user account creation, after user login/logout).
</li>
<li>Define notifications rules based on user attributes values.</li>
<li>Purge user roles before applying user role rules.</li>
<li>Define user account expiration rules bases on CAS User attributes.</li>
<li>Network activation allowed</li>
<li>You can set Service Logout URL (Needs to have CAS Server with followServiceRedirects option configured).</li>
<li>Add support for web application hosted behind a reverse proxy. (Thanks to franck86)</li>
<li>Add custom hooks : wp_cassify_after_cas_authentication, wp_cassify_before_auth_user_wordpress, wp_cassify_before_redirect, wp_cassify_after_redirect. (See online documentation)</li>
<li>Custom filter to perform custom cas server response parsing. Hook name : wp_cassify_custom_parsing_cas_xml_response (See online documentation)</li>
<li>Custom shortcode to generate CAS login/logout link into your blog. (See online documentation)</li>
<li>Debug settings, dump last xml cas server response.</li>
<li>Detect if user has already authenticated by CAS from your public pages and perform auto-login with gateway mode</li>
<li>
Add ‘-IN’ and ‘-NOTIN’ operators to process array attributes values returned from CAS. 
When you have :
<pre><code>$cas_user_datas['title'] = array( 'Student', 'Professor' );
</code></pre>
</li>
</ul>
Then you can use :
<pre><code> (CAS{title} -IN "professor")
</code></pre>
