How to add filter after the HTTP BasicAuthenticationFilter when using @EnableAuthorizationServer

Question

I am trying to go over the following documentation: https://github.com/spring-projects/spring-security-oauth/blob/f25592e682303b0cf89e1d7555174bac18e174df/docs/oauth2.md#mapping-user-roles-to-scopes

In the documentation, it says in order to map user roles to scopes, along with setting the checkUserScopes=true in the DefaultOAuth2RequestFactory, we need to add the TokenEndpointAuthenticationFilter filter after the HTTP BasicAuthenticationFilter. I was wondering how that could be done.

Here is what my AuthorizationServer looks like:

@Configuration
@EnableAuthorizationServer
protected static class OAuth2Config extends
        AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private OAuth2RequestFactory requestFactory;

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        endpoints.authenticationManager(authenticationManager);
        endpoints.requestFactory(requestFactory);
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients)
            throws Exception {
        clients.withClientDetails(clientDetailsService());
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer oauthServer)
            throws Exception {
        oauthServer.checkTokenAccess("isAuthenticated()");
    }

    @Bean
    public ClientDetailsService clientDetailsService() {

        Map<String, ClientDetails> clientDetailsStore = new HashMap<String, ClientDetails>();

        Collection<String> scope = new HashSet<String>();
        scope.add("user");
        scope.add("admin");

        Collection<String> authorizedGrantTypes = new HashSet<String>();
        authorizedGrantTypes.add("password");
        authorizedGrantTypes.add("refresh_token");


        BaseClientDetails clientDetails = new BaseClientDetails();
        clientDetails.setClientId("client");
        clientDetails.setClientSecret("secret");
        clientDetails.setScope(scope);
        clientDetails.setAuthorizedGrantTypes(authorizedGrantTypes);

        clientDetailsStore.put("client", clientDetails);

        InMemoryClientDetailsService clientDetailsService = new InMemoryClientDetailsService();
        clientDetailsService.setClientDetailsStore(clientDetailsStore);

        return clientDetailsService;
    }

    @Bean
    public OAuth2RequestFactory requestFactory() {
        DefaultOAuth2RequestFactory requestFactory = 
                new DefaultOAuth2RequestFactory(clientDetailsService());

        requestFactory.setCheckUserScopes(true);

        return requestFactory;
    }
}

Also, it would be fantastic to provide a sample CURL on how we can test the grant-type password.

Appreciate any help!

Instead of using @EnableAuthorizationServer you should be able to extend AuthorizationServerSecurityConfiguration and include that in your Spring configuration. E.g.

@Configuration
public class OAuth2Config extends AuthorizationServerSecurityConfiguration {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
       super.configure(http);
       http.addFilterAfter(myFilter(), BasicAuthenticationFilter.class);
    }
}
