WindowsAuthenticationEventArgs

System.Web.Security (system.web.dll)sealed class

This class is a custom System.EventArgs that is used in the event handler for the WindowsAuthenticationModule.Authenticate event. It provides three properties: Context, which provides a reference to the current System.Web.HttpContext; User, which will be a null reference and Identity, which will contain the information received from IIS. You can implement a custom authentication scheme and set the User property programmatically to the appropriate user identity. If you don't set it to a non-null value, the WindowsAuthenticationModule creates a System.Security.Principal.WindowsPrincipal object based on the information supplied by IIS and assign it to the System.Web.HttpContext.User property.

The easiest way to set a default identity for impersonation is by using the settings in the web.config file. You should use this event only if you need to implement a custom authentication scheme.
