web applications - Current user with ASP.NET Forms authentication app -

i trying retrieve current user in web application uses asp.net forms authentication. however, system.security.principal.windowsidentity.getcurrent().name returns domain\windowsuser, not username used in formsauthentication.redirectfromloginpage method. using forms authentication in config file:

<authentication mode="forms">       <forms loginurl="views/login.aspx" name=".aspxformsauth" timeout="1" cookieless="useuri">       </forms>     </authentication>     <authorization>       <deny users="?" />     </authorization> 

i trying follow microsoft's walk through , retrieve authentication ticket using following snippet:

    if (request.isauthenticated)     {          var ident = user.identity formsidentity;         if (ident != null)         {              formsauthenticationticket ticket = ident.ticket;             var name = ticket.name;         }     } 

however, ident null because it's windowsidentity not formsidentity. what's wrong here? thank you!

use user.identity.name user name.

windows authentication not use formsauthenticationticket.
