Application Not Authorized to Use IDS

Recently,out project are going to using the CAS. My tutor,ask me to use the third-app cas system,and didn't tell me how to use it. Our System were using the Spring Boot & Spring Security. This is my testing code.

spring:
  cas:
    sign-out-filters: /logout
    auth-filters: /*
    validate-filters: /*
    request-wrapper-filters: /*
    assertion-filters: /*
    cas-server-login-url: https://authserver.xx.cn/authserver/login
    cas-server-url-prefix: https://authserver.xx.cn/authserver
    redirect-after-validation: true
    use-session: true
    server-name: http://xx.natappfree.cc


@Configuration
public class CasConfig {

  private static boolean casEnabled = true;

  private SpringCasAutoConfig autoConfig;

@Bean
public ServletListenerRegistrationBean<SingleSignOutHttpSessionListener> singleSignOutHttpSessionListener() {
    ServletListenerRegistrationBean<SingleSignOutHttpSessionListener> listener = new ServletListenerRegistrationBean<>();
    listener.setEnabled(casEnabled);
    listener.setListener(new SingleSignOutHttpSessionListener());
    listener.setOrder(1);
    return listener;
}

@Bean
public FilterRegistrationBean logOutFilter() {
    FilterRegistrationBean filterRegistration = new FilterRegistrationBean();
    LogoutFilter logoutFilter = new LogoutFilter(autoConfig.getCasServerUrlPrefix() + "/logout?service=" + autoConfig.getServerName(), new SecurityContextLogoutHandler());
    filterRegistration.setFilter(logoutFilter);
    filterRegistration.setEnabled(casEnabled);
    if (autoConfig.getSignOutFilters().size() > 0)
        filterRegistration.setUrlPatterns(autoConfig.getSignOutFilters());
    else filterRegistration.addUrlPatterns("/logout");
    filterRegistration.addInitParameter("casServerUrlPrefix", autoConfig.getCasServerUrlPrefix());
    filterRegistration.addInitParameter("serverName", autoConfig.getServerName());
    filterRegistration.setOrder(2);
    return filterRegistration;
}

        filterRegistration.setUrlPatterns(autoConfig.getRequestWrapperFilters());
    else filterRegistration.addUrlPatterns("/login");
    filterRegistration.setOrder(6);

    else filterRegistration.addUrlPatterns("/*");
    filterRegistration.setOrder(7);
    return filterRegistration;
}
}

And now,if i open localhost:8080,it will redirect to https://authserver.xx.cn/authserver/login?service=http://localhost:8080 But it shows

Application Not Authorized to Use IDS.

Its anybody under such circumstance?
