Apache Module mod_ldap

Description:	LDAP connection pooling and result caching services for use by other LDAP modules
Status:	Extension
Module Identifier:	ldap_module
Source File:	util_ldap.c

Summary

This module was created to improve the performance of websites relying on backend connections to LDAP servers. In addition to the functions provided by the standard LDAP libraries, this module adds an LDAP connection pool and an LDAP shared memory cache.

To enable this module, LDAP support must be compiled into apr-util. This is achieved by adding the --with-ldap flag to the configure script when building Apache.

SSL/TLS support is dependent on which LDAP toolkit has been linked to APR. As of this writing, APR-util supports: OpenLDAP SDK (2.x or later), Novell LDAP SDK, Mozilla LDAP SDK, native Solaris LDAP SDK (Mozilla based) or the native Microsoft LDAP SDK. See the APR website for details.
