This document describes how to enable Active Directory authentication module for Joomla!
Active Directory Login module for Joomla, will allow Joomla sites to have Authentication using an Active Directory Federation Service (ADFS) 2.0 enabled server using the WS Federation Protocol. Using this module Joomla user accounts can be associated with an Active Directory login identity, there by Active Directory credentials can be used to login to Joomla site.
- Joomla 1.5 or 1.6
- PHP 5.2 with mhash & mcrypt and OpenSSL enabled.
- Configure the Joomla site with https so that ADFS can communicate through SSL
- Active directory federation service with Relying party trust set up to your domain/site.
Active Directory Relying Party Configuration
Active directory Relying party configuration is described in a separate document. Please refer to ADFS 2.0 Relying Party Trust Configuration
Relying party endpoint URL should be configured in the relying party configuration. This url is different for joomla 1.5 and joomla 1.6. It is as follows
- Joomla 1.5 - <joomla Base URL>/plugins/authentication/adfshandler.php
- Joomla 1.6 - <joomla Base URL>/plugins/authentication/adfs/adfshandler.php
Joomla base url in the above is the base site url where joomla is configured. The 3 different parameters needed from Active Directory Federation Service to configure the Plugins are as follows
- ADFS Endpoint URL (Eg: https://adfsdemo2.com/adfs/ls)
- SP Identifier/Realm of Relying party trust (Eg: urn:federation:php.cloudapp.com)
- Relying party trust certificate installed
SP Identifier configured in ADFS should exactly match with the one configured in the plugin.

Acceptable certificate format is ‘.pem’. Absolute path of the certificate file on the server should be provided.
