Interface VaadinAuthenticationFailureHandler

public interface VaadinAuthenticationFailureHandler

Strategy used to handle a failed authentication attempt.

Typical behaviour might be to redirect the user to the authentication page (in the case of a form login) to allow them to try again. More sophisticated logic might be implemented depending on the type of the exception. For example, a CredentialsExpiredException might cause a redirect to a web controller which allowed the user to change their password.
