How is 389 different from OpenLDAP?
OpenLDAP and 389 were both derived from the original University of Michigan slapd project. In 1996 the original developers of slapd became Netscape employees and developed Netscape Directory Server, which is now 389. The two projects have a lot in common: support for LDAPv3 including many of the most commonly used controls and extensions; high performance (with the latest revisions of OpenLDAP 2.2.x/2.3 and BerkeleyDB 4.2.x/4.3), some form of replication, multiple back-end support, access control, and others. The OpenLDAP site has a full feature list. Here is a list of the features of 389. We invite the OpenLDAP team to collaborate with 389 and insure cooperation and interoperability between our implementations.
