Single Sign On with Spring Security OAuth2 and JWT - spring-security

Question

I am trying to implement Single Sign On with Spring Security OAuth2 and JWT.
I use two separate applications:
An Authorization Server – which is the central authentication mechanism
Client Application: the applications using SSO
When a user tries to access a secured page in the client app, they’ll be redirected to authenticate first, via the Authentication Server.
And I am using the Authorization Code grant type out of OAuth2 to drive the delegation of authentication.
Authorization server:
#Configuration
#EnableAuthorizationServer
public class OAuth2AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {
public static final Logger LOGGER = LoggerFactory.getLogger(AuthorizationServerConfigurerAdapter.class);
#Autowired
private AuthenticationManager authenticationManager;
#Bean
public TokenStore tokenStore() {
return new JwtTokenStore(accessTokenConverter());
}
#Bean
public JwtAccessTokenConverter accessTokenConverter() {
JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
converter.setSigningKey("abcd");
return converter;
}
#Bean
#Primary
public DefaultTokenServices tokenServices() {
DefaultTokenServices defaultTokenServices = new DefaultTokenServices();
defaultTokenServices.setTokenStore(tokenStore());
defaultTokenServices.setSupportRefreshToken(true);
defaultTokenServices.setTokenEnhancer(accessTokenConverter());
return defaultTokenServices;
}
#Override
public void configure(ClientDetailsServiceConfigurer clientDetailsServiceConfigurer) throws Exception {
clientDetailsServiceConfigurer
.inMemory()
.withClient("webapp")
.secret("Pass")
.authorizedGrantTypes("implicit", "refresh_token", "password", "authorization_code")
.scopes("user_info")
.autoApprove(true);
}
#Override
public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
oauthServer.tokenKeyAccess("permitAll()")
.checkTokenAccess("isAuthenticated()");
}
#Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints
.authenticationManager(authenticationManager);
}
}
Security Configuration on Authorization Server
#Configuration
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {
#Value("${ldap.url}")
private String ldapUrl;
#Value("${ldap.userDnPatterns}")
private String ldapUserDnPatterns;
#Autowired
private PersonService personService;
#Autowired
private RoleService roleService;
#Override
protected void configure(HttpSecurity http) throws Exception { // #formatter:off
http.requestMatchers()
.antMatchers("/login", "/oauth/authorize")
.and()
.authorizeRequests()
.anyRequest()
.authenticated()
.and()
.formLogin()
.permitAll();
} // #formatter:on
#Bean(name = "authenticationManager")
#Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth
.authenticationProvider(this.ldapAndDatabaseAuthenticationProvider());
}
#Bean(name="ldapAuthenticationProvider")
public AuthenticationProvider ldapAndDatabaseAuthenticationProvider(){
LdapUserDetailsMapper userDetailsMapper = new LdapUserDetailsMapper();
userDetailsMapper.setRoleAttributes(new String[]{"groupMembership"});
LdapAndDatabaseAuthenticationProvider provider =
new LdapAndDatabaseAuthenticationProvider(
this.ldapAuthenticator(),
this.ldapAuthoritiesPopulator(),
this.personService);
provider.setUserDetailsContextMapper(userDetailsMapper);
return provider;
}
#Bean( name = "ldapAuthoritiesPopulator" )
public LdapAndDatabaseAuthoritiesPopulator ldapAuthoritiesPopulator(){
return new LdapAndDatabaseAuthoritiesPopulator(this.contextSource(), "", roleService);
}
#Bean( name = "ldapAuthenticator" )
public LdapAuthenticator ldapAuthenticator() {
BindAuthenticator authenticator = new BindAuthenticator( this.contextSource() );
authenticator.setUserDnPatterns(new String[]{"cn={0},ou=prod,o=TEMP"});
return authenticator;
}
#Bean( name = "contextSource" )
public DefaultSpringSecurityContextSource contextSource() {
DefaultSpringSecurityContextSource contextSource =
new DefaultSpringSecurityContextSource( ldapUrl );
return contextSource;
}
}
application.properties:
server.port=8888
server.context-path=/auth
security.basic.enabled=false
When I login the client application, It correctly forwards to Authorization Server for Single Sign On.
I enter the user credentials. User successfully get authenticated, but then I see the below error on browser:
OAuth Error
error="invalid_grant", error_description="A redirect_uri can only be
used by implicit or authorization_code grant types."
URL Shows:
http://localhost:8888/auth/oauth/authorize?client_id=webapp&redirect_uri=http://localhost:8080/jwt/webapp&response_type=code&state=LGvAzj
I also see the below at the log:
02:14:43.610 [http-nio-8888-exec-6] DEBUG o.s.s.o.p.e.FrameworkEndpointHandlerMapping/getHandlerInternal Looking up handler method for path /oauth/authorize

Can you please help me to find the problem?
UPDATE
Actually, Dur is right. This configuration is correct and works fine. I had another configuration file which configures JdbcClientDetails and it was overwriting the clientDetailsService created with inmemory in this configuration.
