Production Release: 03 April 2010
mod_psldap© was created to provide a secure, reliable means of performing authentication of Apache users against an LDAP server. A logical extension of this functionality is to also provide users with the ability to maintain their accounts through a web based ldap browser. mod_psldap© is maintained on SourceForge by PSInd, LLC. mod_psldap© is a C module for Apache based on the Apache & OpenLDAP development libraries.
While evaluating the hordes of OpenSource implementations, we found that many modules would not function with our corporate LDAP server as configured. The problem was that many implementations require the password to be passed out of the LDAP server to the web server for comparison, which goes against a basic concept of limiting sensitive data availability to only those systems that require such access. Moreover, most implementations required administrative access with the initiation of the connection to the LDAP server itself not necessarily being established in a secure fashion.
mod_psldap© started off as a series of minor modifications to Alexander Mayrhofer’s mod_auth_ldap module, which was the closest implementation to providing the features and functionality that were required. When we submitted our changes for inclusion in the package, Alexander stated he was no longer maintaining the package – so mod_psldap was born. The first public release of mod_psldap contains very little of the original source code from the original mod_auth_ldap module, but due credit should be given to Alexander for providing the initial implementation.

Refer to the HOWTO document
The following images represent various screenshots of the sample UI provided with mod_psldap. These screens are rendered against the XML returned to the browser by the module applying the XSL selected by the user when a query is formed. Some static XML documents exist on the server to provide a means of creating new records in the LDAP server, and are represented by the screenshots of the new XXX screens.
