OpenDJ is a directory server which implements a wide range of Lightweight Directory Access Protocol and related standards, including full compliance with LDAPv3 but also support for Directory Service Markup Language (DSMLv2). Written in Java, OpenDJ offers multi-master replication, access control, and many extensions. OpenDJ began as a fork of OpenDS, an LDAP / DSML server which originated in 2005 as an internal project at Sun Microsystems started by Neil A. Wilson, and later grew into an open source project, maintained by Oracle Corporation; following Oracle's acquisition of Sun, OpenDJ is the main trunk developed ForgeRock and maintained by Open Identity Platform Community. OpenDJ source code and binary distribution are available under the Common Development and Distribution License (CDDL).
