WebLogic Server offers the
      following types of Authorization providers:
      
        - The XACML Authorization provider
        is the standard Authorization provider for the WebLogic Security
        Framework. It implements XACML 2.0, the standard access control policy
        markup language.
- The WebLogic Authorization provider is an Authorization
        provider for the WebLogic Security Framework that implements a

        by default instead.
- The Realm Adapter Authorization
