Ticket 47665 - Create new instance results in setting wrong ACI for the "cn=config" entry
    
    Bug Description:  When creating a new instance, ds_create uses the wrong uid
                      for the admin user.
    
    Fix Description:  If the admin user is not set, then try and query it from the CGI
                      request, if that fails, then use the current logged in entry.
