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.^{[citation needed]} In late 2016 the project merged experimental FreeBSD support.^[1] However, the 389 Directory Server team, as of 2017, is likely to remove HPUX and Solaris support in the upcoming 1.4.x series.^[2]

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.
