389 Directory Server

389 Directory Server

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.

389 Directory Server supports:

  • Linux - Directory Server builds on:
    • Fedora 4 and later (x86 and x86_64)
    • Red Hat Enterprise Linux 3 and later (x86 and x86_64)
    • others - Debian, Gentoo, Ubuntu, more
  • Solaris 2.8, 2.9 (32 bit and 64 bit) (Sparc)

  • 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
