Active Directory with ASP.NET

ADSI (Active Directory Services Interface) provides a useful set of interfaces for accessing network providers. As most ASP/ASP.NET programmers will operate in a predominantly Microsoft environment, this article will focus on using ADSI to access Active Directory. However, these concepts can be easily migrated to any LDAP provider. With ADSI, searching and manipulating Active Directory Directory Services has always been relatively easy. However, as with most things in .NET, those tasks have just become easier. In this article, Noel Simpson examines how to traverse and manipulate Active Directory using .Net's System.DirectoryServices namespaces and its two component classes DirectoryEntry and DirectorySearcher. This article assumes that you know what a directory service is and you are somewhat comfortable with Active Directory and its object hierarchy. In order to run the code contained in this article you will need to be running Active Directory.
