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