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.

WP-LDAP

Translates the WordPress user database to an LDAP store of the same; manage your LDAP DIT using your WordPress Dashboard.

THIS IS FOR DEVELOPMENT PURPOSES, NOT FOR USE ON PRODUCTION SITES
This plugin is meant to be a reference; I’ve talked to several people who have similar setups, and thought it would beneficial to share some code.
This plugin allows users to be authenticated via CAS, and logins to be controlled via LDAP. Default user roles can be assigned based on LDAP group membership, and accounts can be auto-created for users that exist in LDAP, but not yet in WordPress.
It assumes that, for CAS authentication, the user is redirected to an outside address, then back to the referring address; that’s how it works where I’m at :-). You can also specify a group in LDAP that will always have admin privileges; useful for tech staff.
Before the plugin is used, the constants in <code>soj-ldap_constants.inc.php</code> must be filled out. The CAS default password is the one the user is registered with in WordPress; so all WP users will have this password. Be aware of that. There is obviously more that could be done there, and I’m happy to work with others who have ideas.
I’ve adapted this from an in-house plugin I made, so there might be leftover code bits or things that look strange… feel free to harass me about that, I did this in a bit of a rush.
I’ve only ever used this plugin on one environment, so it might not work out-of-the-box for you. I’m interested in making this plugin more robust, however, so please let me know of any issues.
