LDAP Tools/Single Sign On
From Authentication Tools for Joomla! (JAuthTools)
The Single Sign On bot is written specifically to integrate Joomla! 1.0.x installs into a Novell Directory Services based network. It is possible using other means to match this if you can configure your LDAP provider to expose a networkAddress attribute matching the IP of the users machine.
This bot is suggested to be used only internally on a corporate network and not out in the real world. In addition this bot will not activate for the back end administrator.
Note: For Joomla! 1.5, please use the new SSO system.
