The enterprise-class Open Source LDAP server for Linux. It is hardened by real-world use, is full-featured, supports multi-master replication, and already handles many of the largest LDAP deployments in the world. The 389 Directory Server can be downloaded for free, and set up in less than an hour using the graphical console.
High performance LDAP server that can handle thousands of operations a second, and tens of thousands of concurrent users.
An open source, real-world, hardened stable directory service. As well as a rich feature set of fail-over and backup technologies.
With a database size that is only restricted by diskspace, high throughput performance, ease of expansion, and multimaster replication, the 389 Directory Server can meet the highest demands.
