/userinfo endpoint missing

[bjornharvold]

I'm not sure whether I should mark this as a feature request or a bug request. I'm also not sure if I a missing something. As this is a new feature, I am trying to figure out how this is done correctly.

Describe the bug
When looking at the openid-configuration document, the userinfo endpoint is not present.

To Reproduce
I've enabled the user info as described in OidcUserInfoTests.java. Specifically:

@Bean
	@Order(Ordered.HIGHEST_PRECEDENCE)
	public SecurityFilterChain authorizationServerSecurityFilterChain(HttpSecurity http, CorsConfigurationSource corsConfigurationSource) throws Exception {
		final OAuth2AuthorizationServerConfigurer<HttpSecurity> authorizationServerConfigurer =
				new OAuth2AuthorizationServerConfigurer<>();

		authorizationServerConfigurer
				.authorizationEndpoint(authorizationEndpoint ->
						authorizationEndpoint.consentPage(CUSTOM_CONSENT_PAGE_URI)
				);

		final RequestMatcher endpointsMatcher = authorizationServerConfigurer
				.getEndpointsMatcher();

		// Custom User Info Mapper that retrieves claims from a signed JWT
		final Function<OidcUserInfoAuthenticationContext, OidcUserInfo> userInfoMapper = context -> {
			OidcUserInfoAuthenticationToken authentication = context.getAuthentication();
			JwtAuthenticationToken principal = (JwtAuthenticationToken) authentication.getPrincipal();

			return new OidcUserInfo(principal.getToken().getClaims());
		};
		
		http
				.cors().configurationSource(corsConfigurationSource)
				.and()
				.requestMatcher(endpointsMatcher)
				.authorizeRequests(authorizeRequests ->
						authorizeRequests.anyRequest().authenticated()
				)
				.csrf(csrf -> csrf.ignoringRequestMatchers(endpointsMatcher))
				.oauth2ResourceServer(OAuth2ResourceServerConfigurer::jwt)
				.apply(authorizationServerConfigurer)
				.oidc(oidc -> oidc
						.userInfoEndpoint(userInfo -> userInfo
								.userInfoMapper(userInfoMapper)
						)
				);

		return http.build();
	}

Expected behavior
The /userinfo endpoint should be present under the openid_configuration document for external libraries to consume.

@bjornharvold, thanks for your interest in the project! I believe this is a duplicate of #488 (though the description does not mention openid-configuration specifically). I'm going to close this as a duplicate for now, but let me know if you feel I've missed anything.
