29 * The Default Authenticator Factory.
30 * Uses the {@link AuthConfiguration#getAuthMethod()} to select an {@link Authenticator} from: <ul>

32 * <li>{@link org.eclipse.jetty.security.authentication.DigestAuthenticator}</li>
33 * <li>{@link org.eclipse.jetty.security.authentication.FormAuthenticator}</li>
34 * <li>{@link org.eclipse.jetty.security.authentication.ClientCertAuthenticator}</li>
35 * </ul>
36 * All authenticators derived from {@link org.eclipse.jetty.security.authentication.LoginAuthenticator} are
37 * wrapped with a {@link org.eclipse.jetty.security.authentication.DeferredAuthentication}
38 * instance, which is used if authentication is not mandatory.
39 *
40 * The Authentications from the {@link org.eclipse.jetty.security.authentication.FormAuthenticator} are always wrapped in a
41 * {@link org.eclipse.jetty.security.authentication.SessionAuthentication}
42 * <p>
43 * If a {@link LoginService} has not been set on this factory, then
44 * the service is selected by searching the {@link Server#getBeans(Class)} results for
45 * a service that matches the realm name, else the first LoginService found is used.
