Say I have the following web.config:

Answer 1

The mode property from the authenticationsection: AuthenticationSection.Mode Property (System.Web.Configuration). And you can even modify it.

// Get the current Mode property.
AuthenticationMode currentMode = 
    authenticationSection.Mode;

// Set the Mode property to Windows.
authenticationSection.Mode = 
    AuthenticationMode.Windows;
