Apache Directory

Apache Directory is an open source project of the Apache Software Foundation. The Apache Directory Server, originally written by Alex Karasulu, is an embeddable directory server entirely written in Java. It was certified LDAPv3-compatible by The Open Group in 2006. Besides LDAP, the server supports other protocols as well.

 * Apache SCIMple - an implementation of SCIM v2.0 specification.
 * Apache Fortress - a standards-based authorization system.
 * Apache Kerby - a Kerberos implementation written in Java.
 * Apache LDAP API - an SDK for directory access in Java.
