Current user with ASP.NET Forms authentication app

Question

I am trying to retrieve the current user in my web application that uses ASP.NET Forms authentication. However, System.Security.Principal.WindowsIdentity.GetCurrent().Name returns domain\windowsUser, NOT the username that was used in the FormsAuthentication.RedirectFromLoginPage method. I am using Forms authentication in my config file:

<authentication mode="Forms">
      <forms loginUrl="Views/Login.aspx" name=".ASPXFORMSAUTH" timeout="1" cookieless="UseUri">
      </forms>
    </authentication>
    <authorization>
      <deny users="?" />
    </authorization>

I am also trying to follow Microsoft's walk through and retrieve the Authentication ticket using the following snippet:

    if (Request.IsAuthenticated)
    {
         var ident = User.Identity as FormsIdentity;
        if (ident != null)
        {

            FormsAuthenticationTicket ticket = ident.Ticket;
            var name = ticket.Name;
        }
    }

However, ident is always null because it's WindowsIdentity not FormsIdentity. What's wrong here? Thank you!

Use User.Identity.Name to get the user name.

Windows authentication does not use the FormsAuthenticationTicket.

User.Identity.Name also returns the same domain\windowsUser NOT the ASP.NET user. User.Identity is of Type WIndowsIdentity and the AuthenticationType is set to "Negotiate". – laconicdev May 09 '13 at 18:48
what authentication system are you using in your web.config? forms or windows? – Daniel A. White May 09 '13 at 18:59
Forms. Here is a snippet: – laconicdev May 09 '13 at 19:48
and how are you authenticating people? – Daniel A. White May 09 '13 at 20:01
Using my own code to check password. If the check is successful, I call this: FormsAuthentication.RedirectFromLoginPage(userName, rememberUser.Checked); – laconicdev May 09 '13 at 21:16
