Get domain\user in a intranet using authentication mode = “forms”

Question

I have to install a ASP.NET site in a intranet network. I'm using a authentication mode=Forms". In a my page i need to get the domain\\user of the user connected.

I've followed this article: http://support.microsoft.com/kb/306359

But it doesn't work. My web.config has:

 <identity impersonate="true"/>
<authentication mode="Forms" >
          <forms name="login" loginUrl="~/Login.aspx" defaultUrl="~/Default.aspx" timeout="30000" />
</authentication>  
<authorization>      
  <deny users = "?" />
  <!-- This denies access to the Anonymous user -->
  <allow users ="*" />
  <!-- This allows access to all users -->
</authorization>

I'm using IIS 6 and .net 4 In Authentication methods settings of iis i've checked

-Enable anonymous access
-Integrated windows authentication

How can i do?

thanks

If you have anonymous access enabled the web-site visitors will all be impersonating the IUSR_MachineName account (or whatever you have configured as the anonymous account).

You need to disable anonymous access so the site will force the user to authenticate with his/her credentials so they will be available in your ASP.NET page. Otherwise the server has no idea who the current user is.
