The extended form of a distinguished name includes a string representation of the objectGUID property of an object. For security principal objects such as users, groups, and computers, the extended form also includes a string representation of the objectSID property. For more information about the objectGUID and objectSID properties, see the topics Object-Guid and Object-Sid in the MSDN Library at http://msdn.microsoft.com/library.

The following C# example shows how to return a collection of distinguished names in hexadecimal format.

using System.DirectoryServices;
...
DirectorySearcher src = new DirectorySearcher("…");
src.PropertiesToLoad = new string[] {ntSecurityDescriptor,…};
src.ExtendedDN = ExtendedDN.HexString;
SearchResultCollection res = src.FindAll();
