389DirectoryServer – enterprise-class Open Source LDAP server for Linux

The 389 Directory Server (previously Fedora Directory Server) is an open source LDAP (Lightweight Directory Access Protocol) server developed by Red Hat, as part of Red Hat’s community-supported Fedora Project. 389 Directory Server is hardened by real-world use, is full-featured, supports multi-master replication, and is reported to handle many of the largest LDAP deployments in the world.

389 Directory Server is mature software; the codebase has been developed and deployed continuously by the same team for more than a decade.

Features include:

  • Java-based GUI front end for administration.
  • Multi-master capability – the ability to write to two or more masters at the same time, with automatic conflict resolution.
  • Uses the Berkeley Database as its data store. This data store is very high performance and is transacted to ensure ACID data updates.
  • Powerful access control mechanism.
  • SSLv3/TLSv1 secure communications over the network including ciphers with up to 256-bit encryption.
  • SASL – Simple Authentication and Security Layer.
  • Support for LDAPv3.
  • Attribute encryption.
  • Ability to export parts of the directory to read-only servers.
  • Password Policy and Account Lockout.
  • Chaining and referrals.
  • Extend the functionality of the server using a well defined C/C++ interface
  • Correctly sorts 38 languages; you can use plug-in handlers for foreign languages that Directory Server does not already sort.
  • Data Interoperability Plugins.
  • DSML Gateway – a SOAP/HTTP based protocol for communicating with directory services.
  • On-line, zero downtime, LDAP-based update of schema, configuration, management and in-tree Access Control Information (ACIs).
  • On line configuration and management.
