Wrong authentication after changing user's logon name

问题

We have a user who recently changed name.

Let's say the old username was old.name and the new username is new.name.

After editing the details in AD and logout/login with the new user name, our ASP.NET application shows the old name.

Plain ASP.NET, no MVC, using Windows authentication.

The code for getting the user name is:

WindowsPrincipal wp = (WindowsPrincipal)HttpContext.Current.User;
String userName = wp.Identity.Name.Substring(wp.Identity.Name.IndexOf("\\") + 1);

This returns old.name, not new.name.

I checked the IIS log files, these show the new name:

2011-04-05 11:41:44 W3SVC1 MARS 10.57.1.64 GET /eft/Default.aspx - 80 - 10.57.0.161 Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.2;+Trident/4.0;+.NET+CLR+1.1.4322;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.4506.2152;+.NET+CLR+3.5.30729;+.NET4.0C;+.NET4.0E) 401 2 2148074254

2011-04-05 11:41:44 W3SVC1 MARS 10.57.1.64 GET /eft/Default.aspx - 80 SANOMABP\new.name 10.57.0.161 Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.2;+Trident/4.0;+.NET+CLR+1.1.4322;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.4506.2152;+.NET+CLR+3.5.30729;+.NET4.0C;+.NET4.0E) 200 0 0

We have restarted the application pool, we have checked the AD data, and we have no more ideas what could be wrong.
