ApacheDS is an embeddable, extendable, standards compliant open source LDAP server entirely written in Java, which has been certified LDAPv3 compatible by the Open Group. Other network protocols like Kerberos5 and NTP as well and the Change Password Protocol are supported. It has been designed to introduce triggers, stored procedures, queues and views to the world of LDAP which has lacked these rich constructs.
It is possible to configure, start and stop ApacheDS from other Java components, especially application servers, and the server runs within the same VM.
ApacheDS 2.0 adheres to all RFCs relevant to LDAPv3.
- Designed as an LDAP and X.500 platform; pluggable components and subsystems make ApacheDS extremely modular and ideal for experiments with various aspects of the LDAP protocol.
- Frontend is completely separable from its backend and vice-versa making it very flexible for implementing virtual directories, proxy servers and gateways to X.500 directories.
- Several backends can be implemented and plugged into the server’s partition nexus. The server supports a BTree based partition out of the box but any backing store can be used to implement a partition as long as it conforms to interfaces.
- The server exposes aspects of administration via a special system backend. LDAP can be used to manage these concerns through the system naming context at ou=system.
- The server contains a server side JNDI LDAP provider as the facade for the entire backend subsystem. JNDI operations are directly translated by this provider into operations against the nexus and the target partitions storing server entries.
- The server’s networking code, MINA (Multipurpose Infrastructure for Network Applications) was designed for pluggable protocol providers, of all sorts and not just LDAP. MINA gives ApacheDS the ability to handle large amounts of concurrency.
- LDAP Stored Procedures and Triggers are scheduled for the next major version of ApacheDS.
- LDAPv3 compatible certified by the OpenGroup.
