Get Active Directory User’s GUID and SID in C#? (Part 1)
Get the Current User’s Active Directory info?
Here is how to get the currently logged in users Active Directory GUID and SID.
Step 1 – Create a new Console Application project in Visual Studio.
Step 2 – Add a .NET reference to System.DirectoryServices.AccountManagement.
Step 3 – Populate the Main Method as shown below.
using System;
using System.DirectoryServices.AccountManagement;
namespace GetAdUserInfo
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Name: " + UserPrincipal.Current.Name);
Console.WriteLine("User: " + UserPrincipal.Current.UserPrincipalName);
Console.WriteLine("GUID: " + UserPrincipal.Current.Guid);
Console.WriteLine(" SID: " + UserPrincipal.Current.Sid);
}
}
}
I'm looking for a way to obtain a "machine id" for every computer in the world. It needs to be unique (as possible). How stable, and how unique is the Current.Sid value?
If it is not suitable as a unique machine identifier...is there a way to obtain one through a different method?
Thanks for your help
