Active Directory Server with .Net

Question

We are developing our application using MS Visual Studio 2008 VB .Net.

We have to use Active Directory Server for authenticating the user logging into the application.

Does any one has code samples intergrating .Net and ADS?

Answer 1

There's the CodeProject articles on the topic:

• Working with Active Directory from VB.NET
• How to do almost anything with Active Directory

and on MSDN in the System.DirectoryServices documentation, there's

• Quicklist of Visual Basic 2005 samples

and then the two really good articles on new features in AD support with .NET 2.0 and 3.5:

• New Ways to Manage Active Directory in .NET 2.0
• Managing Security Principals with .NET 3.5

Hope it helps.

Assuming you are going to put users into an Active Directory Group for authentication:

' Assume an Active Directory group exists named "MyApp Admins" with users in it.
If My.User.CurrentPrincipal.IsInRole("MyApp Admins") Then
   ' Do stuff
End If
