  ****************************************************************
  When a subscription object is created by an administrator, the
  default behavior is fill the SUBUSER attribute of the new
  object with the user ID of the current administrator.
  
  Customers may wish to override this behavior and specify a
  default user ID to be used for new SUB objects. After applying
  the PTF for APAR PM89868, the SYSTEM.DEFAULT.SUB object
  will be checked when defining a new SUB object. If it is not
  blank and the DEFINE command has not explicitly specified a
  SUBUSER attribute then the default SUBUSER value from the
  SYSTEM.DEFAULT.SUB object will be used instead of the current
  administrators ID.
  
  If the SYSTEM.DEFAULT.SUB does not have a SUBUSER value set
  then the behavior will remain as before.
  

Problem conclusion

• DEFINE SUB processing has been amended to consider the value of
  the SUBUSER attribute in the SYSTEM.DEFAULT.SUB object when
  defining new SUB objects.
  
  In the WebSphere MQ Information Center, the page
  that describes the Publish/subscribe security
  to be updated with the information described below:

  topic/com.ibm.mq.doc/ps19550_.htm
  
  "Table 2. User IDs used for security checks for commands" is
  updated as follows:
  
  DEFINE LIKE:
    SUBUSER specified and blank:
      Use the administrator ID
  
    SUBUSER specified and completed:
      Use the user ID specified in SUBUSER
  
    SUBUSER not specified:
      Use the user ID from the LIKE subscription
  
  
  DEFINE with no LIKE:
    SUBUSER specified and blank:
      Use the administrator ID
  
    SUBUSER specified and completed:
      Use the user ID specified in SUBUSER
  
    SUBUSER not specified:
      Use the user ID from the SYSTEM.DEFAULT.SUB subscription -
      if blank, use the administrator ID
  
  
  ALTER:
    SUBUSER specified and blank:
      Use the administrator ID
  
    SUBUSER specified and completed:
      Use the user ID specified in SUBUSER
  
    SUBUSER not specified:
      Use the user ID from the existing subscription
