30 * Thrown from {@link UserDetailsService#loadUserByUsername(String)}
31 * to indicate that the underlying {@link SecurityRealm} is incapable
32 * of retrieving the information, and furthermore, the system cannot
33 * tell if such an user exists or not.
34 *
35 * <p>
36 * This happens, for example, when the security realm is on top of the servlet implementation,
37 * there's no way of even knowing if an user of a given name exists or not.
