How to use RemoteTokenService?

Question

I have a separate ResourceServer built using Spring-Security-oauth2. Here is the code RemoteTokenService.

@Bean
public ResourceServerTokenServices tokenService() {
   RemoteTokenServices tokenServices = new RemoteTokenServices();
   tokenServices.setClientId("sample_test_client_app");
   tokenServices.setClientSecret("secret");
   tokenServices.setCheckTokenEndpointUrl("http://localhost:8080/oauth/check_token");
   return tokenServices;
}

When I'm accessing the resource server with AccessToken I get the following:

FilterSecurityInterceptor - Secure object: FilterInvocation: URL: /oauth/check_token; Attributes: [denyAll()]
FilterSecurityInterceptor - Previously Authenticated: org.springframework.security.authentication.UsernamePasswordAuthenticationToken@c3f3b25: Principal: org.springframework.security.core.userdetails.User@3c0cd8e: Username: sample_test_client_app; Password: [PROTECTED]; Enabled: true; AccountNonExpired: true; credentialsNonExpired: true; AccountNonLocked: true; Not granted any authorities; Credentials: [PROTECTED]; Authenticated: true; Details: org.springframework.security.web.authentication.WebAuthenticationDetails@957e: RemoteIpAddress: 127.0.0.1; SessionId: null; Not granted any authorities
AffirmativeBased - Voter: org.springframework.security.web.access.expression.WebExpressionVoter@6172e10, returned: -1
ExceptionTranslationFilter - Access is denied (user is not anonymous); delegating to AccessDeniedHandler

Can any one tell me what is wrong with my configuration ?

Update : My Spring security configuration.

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {

        auth.inMemoryAuthentication().withUser("developer").password("developer").roles("USER");

    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/webjars/**", "/images/**", "/oauth/uncache_approvals", "/oauth/cache_approvals");
    }

    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // @formatter:off
                 http
            .authorizeRequests().antMatchers("/login.jsp").permitAll().and()
            .authorizeRequests().antMatchers("/oauth/check_token").permitAll().and()
            .authorizeRequests()
                .anyRequest().hasRole("USER")
                .and()
            .exceptionHandling()
                .accessDeniedPage("/login.jsp?authorization_error=true")
                .and()
            .logout()
                .logoutSuccessUrl("/index.jsp")
                .logoutUrl("/logout.do")
                .and()
            .formLogin();
        // @formatter:on
    }
}

My Auth server configuration.

@Configuration
    @EnableAuthorizationServer
    protected static class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

        @Autowired
        private TokenStore tokenStore;

        @Autowired
        private UserApprovalHandler userApprovalHandler;

        @Autowired
        @Qualifier("authenticationManagerBean")
        private AuthenticationManager authenticationManager;

        @Override
        public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
            // @formatter:off
            clients
                .inMemory()
                .withClient("sample_test_client_app")
                .secret("secret")
                .authorizedGrantTypes("client_credentials","authorization_code")
                .authorities("ROLE_CLIENT")
                .resourceIds(CHANAKYA_RESOURCE_ID)
                .scopes("read","write");

            // @formatter:on
        }

        @Bean
        public TokenStore tokenStore() {
            return new InMemoryTokenStore();
        }

        @Override
        public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
            endpoints.tokenStore(tokenStore).userApprovalHandler(userApprovalHandler)
                    .authenticationManager(authenticationManager);
        }

        @Override
        public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
            oauthServer.realm("resource_server/client");
        }

    }

Answer 1

I have the following configuration:

@Configuration
@EnableWebSecurity
@EnableAuthorizationServer
public class OAuthSecurityConfig extends AuthorizationServerConfigurerAdapter {
// ...
    @Override
    public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        // (!)
        oauthServer.allowFormAuthenticationForClients();
    }
// ...

I added the following line:

    oauthServer.checkTokenAccess("permitAll()");

into the line with "(!)" to fix the same problem.
