In a WebLogic resource adapter,
      you can either have a single security identity that can perform all
      functions, or use separate identities for separate classes of functions.
      You can define the following four types of security identities in the
      weblogic-ra.xml deployment descriptor:
      
          - default principal: a security principal that can perform all
          resource adapter tasks
 
          - run-as principal: a security principal used by calls from the
          connector container into the resource adapter code during connection
          requests.
 
          - run-work-as principal: a security principal used for Work
          instances launched by the resource adapter.
 
          - manage-as principal: a security principal used for resource
          adapter management tasks, such as startup, shutdown, testing, and
          transaction management.
