OpenLDAP

OpenLDAP is a free, open-source implementation of the Lightweight Directory Access Protocol (LDAP) developed by the OpenLDAP Project. It is released under its own BSD-style license called the OpenLDAP Public License. LDAP is a platform-independent protocol. Several common Linux distributions include OpenLDAP Software for LDAP support. The software also runs on BSD-variants, as well as AIX, Android, HP-UX, macOS, OpenVMS, Solaris, Microsoft Windows (NT and derivatives, e.g. 2000, XP, Vista, Windows 7, etc.), and z/OS. The OpenLDAP project was started in 1998 by Kurt Zeilenga. The project started by cloning the LDAP reference source from the University of Michigan where a long-running project had supported development and evolution of the LDAP protocol until that project's final release in 1996. As of May 2015, the OpenLDAP project has four core team members: Howard Chu (chief architect), Quanah Gibson-Mount, Hallvard Furuseth, and Kurt Zeilenga. There are numerous other important and active contributors including Ondrej Kuznik, Luke Howard, Ryan Tandy, and Gavin Henry. Past core team members include Pierangelo Masarati.
