This article is second in the series demonstrating the use of Active Directory
in ASP.Net. The first article Using Active Directory In ASP.Net
- Dump Schema Informations demonstrated how to get the schema
information. In this article we will use the basics discussed earlier to
enumerate the Active Direftory users.
This article demonstrates the use of following namespaces and classes.
- System.DirectoryServices
- System.DirectoryServices.DirectoryEntry
- System.DirectoryServices.DirectorySearcher
- System.DirectoryServices.SearchResultCollection
- System.DirectoryServices.SearchResult
- System.DirectoryServices.ResultPropertyCollection
- System.DirectoryServices.PropertyValueCollection
The basics steps to implement the enumeration of Active Directory Users remain
the same as discussed in the first article, Using Active Directory In ASP.NET - Dump Schema Information. The only
difference is the query that is used to search for the Users.
We have added a new method, GetUsersList in ADSIUtil class.
This method sets the appropriate search criteria filter to look for all the
Active Directory Users. To get the list of Users, the filter is set to look for User
object class.
SearchResultCollection results;
DirectorySearcher srch = new DirectorySearcher(m_obDirEntry);
srch.Filter = "(objectClass=User)";
results = srch.FindAll();
Platforms Tested
We have tested the included project on following platforms
- Windows 2000 Adv. Server
- Windows .NET Enterprise Server (Beta 3)
