What is "opends"

OpenDS Software is a free, open source directory service, written in Java, and developed as part of the OpenDS project. OpenDS Software implements a wide range of Lightweight Directory Access Protocol (LDAP) and related standards, including full compliance with LDAPv3 but also support for Directory Service Markup Language (DSMLv2). It also offers multi-master replication, access control, and many extensions.

OpenDS software is released under Sun Microsystems's Common Development and Distribution (CDDL) License. LDAP and DSML are platform-independent protocols. The software is developed and runs on any system with Java programming language support, including common Linux and UNIX distributions, Microsoft Windows, Mac OS X, and others. The documentation for OpenDS is presented as a Wiki.
