Question

Get Username in ASP.NET site using Windows Integrated Authentication

Asked by: ideamatics

I have developed an ASP.NET 3.5 web application which is hosted on Windows 2003 Server using IIS 6.  In my application, I need to get the user name of the person accessing the site.  In IIS, I have the site configured so that it does not use Anonymous access and the Windows Integrated checkbox is checked.  So when the user enters the site, they enter their credentials.  great.  But I cannot seem to extract the user name.  I have read many posts and tried many methods, but can't seem to get it.  Take a look at the screenshot to see all the different methods I tried.  

Label1.Text = Request.ServerVariables("Auth_User")
        Label2.Text = System.Web.HttpContext.Current.Request.LogonUserIdentity.Name
        Label3.Text = HttpContext.Current.User.Identity.Name.ToString()
        Label4.Text = Request.ServerVariables("LOGON_USER")
        Label5.Text = System.Security.Principal.WindowsIdentity.GetCurrent.Name.Replace("\", "/")
        Label6.Text = Request.Form("userName")

they all result in empty strings.  Any ideas?  Please note that this site is configured with a certificate (https).  In my web.config, I have impersonate="true" in the identity tag.  I also have Authentication mode="Windows".  All ideas welcome!  Thanks
