Fedora Directory Server
Encyclopedia
The 389 Directory Server (previously Fedora Directory Server) is an LDAP (Lightweight Directory Access Protocol
) server developed by Red Hat
, as part of Red Hat's community-supported Fedora Project
. 389 Directory Server is identical to the Red Hat Directory Server, just rebranded. The name 389 is derived from the port number for LDAP.
While 389 Directory Server is freely distributable under the terms of the GPL, Red Hat is also offering an officially supported version, Red Hat Directory Server, but with a different license known as open public license. The paid subscription will include added features like certified stable builds, customer service, and technical support, although the paid version is only available in limited markets.
389 Directory Server is being built on top of Fedora
, but supports many operating systems including Red Hat Enterprise Linux
3 and later, Debian
, Solaris 8 and later, and HP-UX

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. 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 all of the remaining source code for all components included in the release package 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.
Since Oracle bought Sun, there has been considerable uncertainty over the future and cost of the Sun/Oracle version of the JES/Sun One Directory Server.
389 Directory Server also has the ability to export parts of the directory to read-only servers. This is similar to the Read Only Domain Controller in Microsoft's Active Directory Domain Services
