OpenDJ is a fork of the OpenDS directory server, with OpenDS originally being developed by Sun. Sun went its own way with JDS, and OpenDS was developed for a while by the community. ForgeRock came along and forked the stale project off (the last OpenDS release was back in 2010) and have been actively developing and since then have been releasing builds as OpenDJ. OpenDJ forms part of the complete ForgeRock open-identity stack, fully supported, and is a very viable alternative to the Sun/Oracle IDM stack. OpenDS, and therefore OpenDJ, are pure Java implementations.
In this article, I will install and configure OpenDJ on two nodes running Oracle Enterprise Linux 5.7 x86_64. OpenDJ will be configured with multi-master replication between both nodes. The same procedure should work on any RHEL 5.x or 6.x derivative. Node names are foo-0001prjenv and foo-0002prjenv.
You should obtain the latest versions of all software for your platform.
