Red Hat releases Netscape Directory Server under the GPL
Red Hat has released the Fedora Directory Server (formerly known as the Netscape Directory Server) under the GPL. This is the same codebase (or was, at one time) that Sun’s iPlanet Directory Server / Sun ONE Directory Server / Java Enterprise System Directory Server is based upon. Source and binary packages are available for both Red Hat Linux and Solaris.
This is a very good information that Fedora Directory Services is on Netscape Directory Server.
