I have a 7.5 IIS .net 4.0 web application, that is configured to use Windows authentication and has ASP.Net impersonation turned on and Anonymous Authentication is turned off. The server is in a different forest/domain to the users workstation but there is a trust relationship between each forest/domain.

When the user logins to the website the WindowsPrincipa l object returns the identity of the App pool.

Does anyone...
