FusionDirectory is an infrastructure management tool built on LDAP that was created by Benoit Mortier. It provides a user-friendly web interface for storing and managing infrastructure data in an LDAP server. This allows infrastructure data to be accessible to various users and roles. FusionDirectory aims to provide a single place to manage the entire complexity of an organization's infrastructure, going beyond just user management. It uses a plugin system and API to make it customizable for any infrastructure needs.
