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.
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.[3][4][5]
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.[6]
