The scenario I had in mind involves iterative resolution of
a groupOfUniqueNames that may in turn contains DNs that
may in turn need resolution...  And some of those DNs might
point at non-existent records depending on how the directory
has been set-up.

Especially in the case of Intranet management of mailing
lists, mail routing, etc.
