[keycloak-user] Policy Enforcement Mode cannot be changed.

Hi Guys, I read from documents, and my understanding is if set Policy Enforcement Mode to disable, then any users can access all resources. but I tried to set it to disable. but nothing be changed. For example, I have a role call Role_A , and set a user Tom as this Role_A, if I set a resource access policy without Role_A. this user Tom cannot access this resource. And I can see some log in tomcat. Oct 26, 2016 7:37:33 PM org.keycloak.adapters.authorization.PolicyEnforcer enforce DEBUG: Policy enforcement is enable.
