This snippet shows how LogonUserIdentity is set (using reflector)

 if ((this._wr is IIS7WorkerRequest) && (((this._context.NotificationContext.CurrentNotification == RequestNotification.AuthenticateRequest) && !this._context.NotificationContext.IsPostNotification) || (this._context.NotificationContext.CurrentNotification < RequestNotification.AuthenticateRequest)))
        {
            throw new InvalidOperationException(SR.GetString("Invalid_before_authentication"));
        }
        IntPtr userToken = this._wr.GetUserToken();
        if (userToken != IntPtr.Zero)
        {
            string serverVariable = this._wr.GetServerVariable("LOGON_USER");
            string str2 = this._wr.GetServerVariable("AUTH_TYPE");
            bool isAuthenticated = !string.IsNullOrEmpty(serverVariable) || (!string.IsNullOrEmpty(str2) && !StringUtil.EqualsIgnoreCase(str2, "basic"));
            this._logonUserIdentity = CreateWindowsIdentityWithAssert(userToken, (str2 == null) ? "" : str2, WindowsAccountType.Normal, isAuthenticated);
        }

As you can see this has been changed for IIS 7. I believe you are using Windows Authentication + Impersonation so I would go with the last one (WindowsIdentity.GetCurrent()) which I am sure is the identity request being run with.
