Apache Directory Server (ApacheDS) is an extensible directory server written in Java, certified LDAPv3 compatible by the Open Group. It supports LDAP, Kerberos 5, and the Change Password Protocol, and can also be embedded in Java applications. Server configuration uses LDIF files; pluggable components and subsystems let different backends be added to its partition nexus. For access control, ApacheDS adapts the X.500 basic access control scheme and uses X.500 subentries to control access to directory entries and attributes. Version 2.0 supports multi-master replication via RFC 4533 and is described as compatible with OpenLDAP. It also supports the LDAP Password Policy draft for enforcing stronger password rules. ApacheDS is free, with a free plan and no free trial, and is listed for Linux, macOS, Windows, and self-hosted use. The project says it is not production ready because of data corruption issues. It identifies testing, development, and education as suitable uses until the issue is fixed, and advises minimizing updates and keeping backups if it is used in production.
