This plugin turns your WordPress Dashboard into a familiar management interface for an enterprise-scale LDAP Directory Information Tree (DIT). Configure a connection to your LDAPv3 directory server, and from then on any modifications you make to your WordPress user database through the WordPress admin screens will be reflected in your LDAP database. This offers a simpler and more convenient front-end for managing user account information to support single sign-on (SSO), identity management, and other enterprise functions.

All user accounts on the WordPress side are mirrored as <a href="https://www.ietf.org/rfc/rfc2798.txt" rel="nofollow ugc"><code>inetOrgPerson</code> (RFC 2798)</a> entries on the LDAP side. The following WordPress user account fields to LDAP attribute translations take place when a new WordPress user is created:
<ul>
<li>The WordPress <code>user_login</code> field becomes the <code>uid</code> attribute in the LDAP database.</li>
<li>The WordPress <code>user_email</code> field becomes the <code>mail</code> attribute in the LDAP database.</li>
<li>The WordPress <code>display_name</code> field becomes the <code>displayName</code> attribute in the LDAP database.</li>
<li>The WordPress <code>user_pass</code> field becomes the <code>userPassword</code> attribute in the LDAP database.</li>
</ul>
There is no mapping for the WordPress user ID number on the LDAP side. Instead, users are uniquely identified by their fully-qualified Distinguished Name (DN). A user’s DN is automatically composed by combining their WordPress <code>user_login</code> with the WordPress Multisite’s configured LDAP Search Base setting. For instance, by default, a WordPress Multisite with WP-LDAP installed running at <code>https://example.com/</code> with a user whose username is <code>exampleuser</code> will automatically be mirrored over LDAP to the user identified as <code>uid=exampleuser,dc=example,dc=com</code>.
In addition to the above mappings, the following optional mappings also take place if or when the user updates their user profile:
<ul>
<li>The WordPress <code>first_name</code> field becomes the <code>givenName</code> attribute in the LDAP database.</li>
<li>The WordPress <code>last_name</code> field becomes the <code>sn</code> attribute in the LDAP database.</li>
<li>The WordPress <code>nickname</code> field becomes the <code>cn</code> attribute in the LDAP database.</li>
<li>The WordPress <code>description</code> field becomes the <code>description</code> attribute in the LDAP database.</li>
<li>The WordPress <code>user_url</code> field becomes the <code>labeledURI</code> attribute in the LDAP database.</li>
<li>The WordPress user’s avatar becomes the <code>jpegPhoto</code> attribute in the LDAP database. (Not yet implemented.)</li>
</ul>
Moreover, WP-LDAP is aware of certain features provided by other plugins. These include:
<ul>
<li>The WordPress user’s S/MIME certificate (<code>smime_certificate</code> field) becomes the <code>userSMIMECertificate</code> attribute in the LDAP database. (This functionality is provided by the <a href="https://wordpress.org/plugins/wp-pgp-encrypted-emails/" rel="ugc">WP PGP Encrypted Emails</a> plugin and that plugin must be installed and activated for this to work.)</li>
</ul>
This plugin is designed for medium to large deployments of WordPress Multisite (or Multi-Network) instances, originally developed as a collaboration with the <a href="https://glocal.coop/activist-network-platform/" rel="nofollow ugc">Glocal Coop’s Activist Network Platform</a> project. If you run multiple WordPress Multisite Networks, you can configure each WP Network with different LDAP settings. This plugin does not currently support single-site installs; please <a href="https://github.com/meitar/wp-ldap/issues" rel="nofollow ugc">post an issue on GitHub</a> if you want to use LDAP data stores with a WP single-site install and we can discuss use cases.

Use your existing LDAP as authentication-backend for your wordpress!
So what are the differences to other WordPress-LDAP-Authentication-Plugins?
<ul>
<li>Flexible: You are totaly free in which LDAP-backend to use. Due to the extensive configuration you can freely decide how to do the authentication of your users. It simply depends on your filters</li>
<li>Independent: As soon as a user logs in, it is added/updated to the WordPress’ user-database to allow wordpress to always use the correct data. You only have to administer your users once.</li>
<li>Failsafe: Due to the users being created in WordPress’ User-database they can also log in when the LDAP-backend currently is gone.</li>
<li>Role-Aware: You can map WordPress’ roles to values of an existing LDAP-attribute.</li>
</ul>
For more Information on the configuration have a look at https://github.com/heiglandreas/authLdap

This plugin is the only one in WP.org which works out of the box, it's super easy to set up and even has user group mapping included. Thanks once again and totally recommended to every one.

Karolina

Works perfectly and has group mapping!
