Как получить информацию о пользователе в контроллере приложения Spring Boot OIDC?

Я адаптировал код из здесь для вызова сервера MitreID OIDC.

Мой контроллер:

    public final String home(Principal p) {
    final String username = SecurityContextHolder.getContext().getAuthentication().getName();
...

возвращает null и имеет значение null для всех сведений о пользователе.

Я также пробовал:

public final String home(@AuthenticationPrincipal OpenIdConnectUserDetails user) {
        final String username = user.getUsername();

а также

@RequestMapping(value = "/username", method = RequestMethod.GET)
    @ResponseBody
    public String currentUserNameSimple(HttpServletRequest request) {
        Principal principal = request.getUserPrincipal();
        return "username: " + principal.getName();
    }

Все пусто, но аутентификация является возвращает токен доступа и пользователя.

Моя конфигурация безопасности:

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private OAuth2RestTemplate restTemplate;

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/resources/**");
    }

    @Bean
    public OpenIdConnectFilter myFilter() {

        final OpenIdConnectFilter filter = new OpenIdConnectFilter("/openid_connect_login");
        filter.setRestTemplate(restTemplate);
        return filter;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        // @formatter:off
        http
        .addFilterAfter(new OAuth2ClientContextFilter(), AbstractPreAuthenticatedProcessingFilter.class)
        .addFilterAfter(myFilter(), OAuth2ClientContextFilter.class)
        .httpBasic().authenticationEntryPoint(new LoginUrlAuthenticationEntryPoint("/openid_connect_login"))
        .and()
        .authorizeRequests()
        .antMatchers("/","/index*").permitAll()
        .anyRequest().authenticated()
        ;

     // @formatter:on
    }
}

Так почему мой контроллер не может получить доступ к данным пользователя?

Обновлено: по запросу, OpenIdConnectFilter:
