Well i were navigating for some sort of a wrapper for an openLDAP directory until i found one that really works

".NET C# LDAP library provides easy access to any LDAP compliant directory from managed code. The library enables the developers to write LDAP enabled applications that access, manage, and update information stored in Novell eDirectory or other LDAP-aware directories. We assume that the user of the library is familiar with general understanding of LDAP before using the class provided in the library. This document provides an overview of the .NET C# LDAP library and programming code examples." by Sunil Kumar
