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.
- 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.
