Having a single login for every service is a must in large organizations. This plugin allows you to integrate WordPress with LDAP quickly and easily. Like, really really easy.

This is a community project now. Most development is done by users like you who find bugs and fix them, or find new ways to make the plugin more powerful for everyone.

The easiest way to contribute to this plugin is to submit a GitHub pull request. Here’s the repo:

  • Supports Active Directory and OpenLDAP (and other directory systems which comply to the LDAP standard, such as OpenDS)
  • Supports TLS
  • Uses up-to-date methods for WordPress authentication routines.
  • Authenticates existing WordPress usernames against LDAP.
  • Can be configured to automatically create WordPress users for valid LDAP logins.
  • You can restrict logins based on one or more LDAP groups.
  • Intuitive control panel.


Simple LDAP Login adds an authentication filter to WordPress that authentication requests must pass. In doing so, it makes several decisions.

  • Can the provided credentials be authenticated against LDAP?
    • If so, is the LDAP user a member of the required LDAP groups (if any)?
      • Does a matching WordPress user exist?
        • If so, log the user in.
        • If not, is user creation enabled?
          • Create the user and log them in.

This is high level overview. This should answer the philosophical questions about how the plugin works. If the plugin is unable to authenticate the user, it should pass it down the chain to WordPress. (Unless LDAP Exclusive is turned on, in which case it won’t.)
