OpenLDAP is the open-source version of LDAP. For a list of Open Client and Open Server platforms that use OpenLDAP libraries, see the Open Server and SDK New Features for Windows, Linux, UNIX, and Mac OS X. More information on configuration can be found in the Open Client and Open Server Configuration Guide for your platform.
The Sybase-provided OpenLDAP library (libsybaseldap.so/dll)
uses OpenLDAP version 2.4.31 and OpenSSL version 1.0.1b for the
connections to an LDAP server.
