title: DirectorySecurity not setting permissions correctly
body: <p>I have a C# code which creates a folder and sets some permissions on it. Here is the code sample:</p>
  
  <pre><code>static void Main(string[] args){
  
          Directory.CreateDirectory("C:\\vk07");
          DirectorySecurity dirSec = Directory.GetAccessControl("C:\\vk07");
  
          dirSec.AddAccessRule(new FileSystemAccessRule("INTRANET\\fGLBChorusUsers", FileSystemRights.ReadAndExecute, AccessControlType.Allow));            
          Directory.SetAccessControl("C:\\vk07", dirSec);
  }
  </code></pre>
  
  <p>When I check the permissions set on the folder created above, instead of having Read and Modify (which is what I have set in the code), it shows only "Special Permissions" as checked.</p>
  
  <p>Please can some one help me with this? I am new to ACL, so don't understand it very well.</p>
