Can access spring oauth2 protected resource without access token

Using :

• spring-security 3.2.5


• spring-security-oauth 2.0.7 (oauth2)


• grant_type : authentication_code

I have no problem getting authentication_code and access token. The problem I have is that if I call a "protected" resource, I can access it with no token at all. Here is the security config of the "not-really-protected" resource :

<security:http pattern="/api/user/**" create-session="never" entry-point-ref="oauthAuthenticationEntryPoint"
                  access-decision-manager-ref="accessDecisionManager">
  <security:anonymous enabled="false" />
  <security:intercept-url pattern="/**" access="IS_AUTHENTICATED_FULLY" />
  <security:custom-filter ref="userResourceServer" before="PRE_AUTH_FILTER" />
  <security:access-denied-handler ref="oauthAccessDeniedHandler" />
</security:http>

The Oauth2AuthenticationProcessingFilter is saying

No token in request, will continue chain.

I found this other post wich seems to describe the same problem, but the solution presented is to add <security:intercept-url pattern="/**" access="IS_AUTHENTICATED_FULLY" />, wich I already have.

Also, tough maybe not related, the request to the protected resource receive à Set-cookie header, defining a jsessionid. It seems not normal to me since I specify create-session="never".

I expected an unauthorized call to this resource to return a 403 since I use OAuth2AccessDeniedHandler.

Can someone help me with this ?

Note that I am pretty sure that this security config is kicking in because in my protected resource(a spring-mvc controller), SecurityContextHolder.getContext().getAuthentication() returns null. If I completely disable the above security config, the same line returns an anonymous authentication.

EDIT : Detailed configuration information.

First I have the token enpoint configuration :

  <security:http pattern="/api/oauth/token" 
               create-session="stateless" 
               authentication-manager-ref="clientAuthenticationManager">
    <security:intercept-url pattern="/api/oauth/token"
                            access="IS_AUTHENTICATED_FULLY" />
    <security:anonymous enabled="false" />
    <security:http-basic entry-point-ref="clientAuthenticationEntryPoint" />
    <security:access-denied-handler ref="oauthAccessDeniedHandler" />
  </security:http>

Then the resource endpoint configuration (as shown at the beginning of the question) :

   <security:http pattern="/api/user/**" 
                  create-session="never" 
                  entry-point-ref="oauthAuthenticationEntryPoint"
                  access-decision-manager-ref="accessDecisionManager">
     <security:anonymous enabled="false" />
     <security:intercept-url pattern="/api/user/**"
                             access="IS_AUTHENTICATED_FULLY" />
     <security:custom-filter ref="userResourceServer"
                             before="PRE_AUTH_FILTER" />
     <security:access-denied-handler ref="oauthAccessDeniedHandler" />
   </security:http>

And then the "generic" url configuration :

<security:http name="genericSecurityConfiguration" entry-point-ref="customLoginEntrypoint">
    <security:form-login authentication-failure-url="/index.jsp"
                         authentication-success-handler-ref="customAuthenticationSuccessHandler"
                         authentication-failure-handler-ref="customAuthenticationFailureHandler"
                         login-page="/index.jsp"
                         login-processing-url="/solapCore/identification2"
                         username-parameter="username"
                         password-parameter="password"
                         />
    <security:session-management invalid-session-url="/index.jsp?invalidSession=true" session-authentication-strategy-ref="sas" /> 
    <security:custom-filter position="LOGOUT_FILTER" ref="logoutFilter"/>
    <security:custom-filter before="FILTER_SECURITY_INTERCEPTOR" ref="monitoringFilter"/>
    <security:access-denied-handler ref="solapcoreAccessDeniedHandler"/>
  </security:http>
