Active Directory and C#

I have done a lot of work in the last few years with AD and C#. I figured now that I shared a whole bunch of AzMan stuff, it is only logical that I share some AD helper classes as well. Some of the code can of course be written differently now in the world of .NET 3.5. However, what is written is still relevant and works well. Like the AzMan posts, this will be a bunch of posts tied together to make an application. Unlike AzMan, this will be slower since there is a A LOT more in AD than in AzMan.

One thing that I'll point out is that I rely on ActiveDS more than DirectoryEntry....so for those against this, I am sorry :)

I'd like to start off with the AdUser class that I use from my AdLibrary which you can download from here:

using System;
using System.Collections.Generic;
using System.Text;
using ActiveDs;
using System.DirectoryServices;

namespace AdLib
{
   public class AdUser : IDisposable
   {
       private DirectoryEntry _entry;
       private IADsUser _user;

       public AdUser(DirectoryEntry entry)
       {
           if (entry == null)
               throw new ArgumentNullException("entry");

           _entry = entry;
           _user = (IADsUser)entry.NativeObject;
       }

       public DirectoryEntry Entry
       {
           get { return _entry; }
       }

       public IADsUser NativeObject
       {
           get { return _user; }
       }

       #region IDisposable Members

       public void Dispose()
       {
           _entry.Dispose();
       }

       void IDisposable.Dispose()
       {
           Dispose();
       }

       #endregion
   }
}

To be honest, not much can be done with this. However, combined with all the other classes in the upcoming posts you will see how it all ties together.
