  How to get windows user ID in C# web application# web application?

  To clarify, I am talking about login ID that user uses to login to his working machine. (he/she has to press Ctrl-Alt-Del and enter login and password to start working)

  I was looking around and one of the suggestion was to use: System.Environment.UserName;

  But, this gives (by my opinion) account name under which the application is logged to the server that hosts application. In my case I get "ASPNET" and that is not my windows ID.

  This only gives my account "domain\srayabharapu" System.Security.Principal.WindowsIdentity.GetCurrent().Name;

  I assume that for this I will have to connect to Active Directory. How can I do that and how to query Active Directory.

  this is needed because i need to add groupusername to set the user for an item.

  Thanks.

  Hi,

  // Ensure Directory Security settings for default web site in IIS is "Windows Authentication".

  string url = "http://localhost";

  // Create a 'HttpWebRequest' object with the specified url.

  HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url);

  // Assign the credentials of the logged in user or the user being impersonated.

  myHttpWebRequest.Credentials = CredentialCache.DefaultCredentials;

  // Send the 'HttpWebRequest' and wait for response.

  HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();

  Console.WriteLine("Authentication successful");

  Console.WriteLine("Response received successfully");

  Hope this code will help you.

  Wish u all the best

  Thanks for the reply.

  string userName = Request.ServerVariables["AUTH_USER"]; //Finding with name

  This is the answer which am looking at.
