Почему он не перенаправляет на сервер аутентификации?

Question

Я пытаюсь защитить свое веб-приложение с помощью Keycloak Jetty 9.x Adapters со следующими конфигурациями в папке WEB-INF:

jetty-web. xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://www.eclipse.org/jetty/configure_9_0.dtd">

                           <Item>password</Item>
                        </Entry>
                     </Map>
                  </Set>
               </New>
            </Set>
         </New>
      </Set>
   </Get>
</Configure>

web. xml

Я запускаю причал на своем локальном компьютере, и он показывает:

Затем я вызываю localhost:8080 в браузере, и он перенаправляет меня на localhost:8443. Почему он не перенаправляет меня на https://dev.oic.example.io/auth/, который я настроил в файле jetty-web. xml.
