      Roles can help you overcome another subtle problem with the
      local manager pattern. The problem is that the local manager
      pattern requires a strict hierarchy of control.  There is no
      provision to allow two different groups of people to access the
      same resources without one group being the manager of the other
      group. Put another way, there is no way for users defined in one
      part of the site to manage resources in another part of the
      site.
