Use Signed in user in application

Hello All,

I have a ASP.net application running on IIS7. I user impersonation with the authenticated user.

The application set's some properties into Active Directory by input from the user. However the application seems to use the application pool user for this, in stead of the logged in user. Does anyone have an idea how to avoid this and that the action is performed with the logged in user account?

Thanks,

Peter
