389 Directory Server

The 389 Directory Server (previously Fedora Directory Server) is a Lightweight Directory Access Protocol (LDAP) server developed by Red Hat as part of the community-supported Fedora Project. The name "389" derives from the port number used by LDAP.

389 Directory Server supports many operating systems, including Fedora Linux, Red Hat Enterprise Linux, Debian, Solaris, and HP-UX 11i. In late 2016 the project merged experimental FreeBSD support. However, the 389 Directory Server team, as of 2017, is likely to remove HPUX and Solaris support in the upcoming 1.4.x series.

The 389 source code is generally available under the GNU General Public License version 3; some components have an exception for plugin code, while other components use LGPLv2 or Apache. Red Hat also markets a commercial version of the project as Red Hat Directory Server as part of support contracts for RHEL.

History
389 Directory Server is derived from the original University of Michigan Slapd project. In 1996, the project's developers were hired by Netscape Communications Corporation, and the project became known as the Netscape Directory Server (NDS). After acquiring Netscape, AOL sold ownership of the NDS intellectual property to Sun Microsystems, but retained rights akin to ownership. Sun sold and developed the Netscape Directory Server under the name JES/SunOne Directory Server, now Oracle Directory Server since the takeover of Sun by Oracle. AOL/Netscape's rights were acquired by Red Hat, and on June 1, 2005, much of the source code was released as free software under the terms of the GNU General Public License (GPL).

As of 389 Directory Server version 1.0 (December 1, 2005), Red Hat released as free software all the remaining source code for all components included in the release package (admin server, console, etc.) and continues to maintain them under their respective licenses.

In May 2009, the Fedora Directory Server project changed its name to 389 to give the project a distribution- and vendor-neutral name and encourage porting or running the software on other operating systems.
