That message is only telling you that ppolicy is not recognized as a
global control; in fact, it's only supported within the naming context you
configured the ppolicy overlay for.  As a consequence, handling of that
control is deferred.  You're simply logging at a too verbose level, and
erroneously interpreting the resulting logs.  The control does nothing in
the operation above likely because there's nothing to do (i.e. you didn't
provide an incorrect password multiple times, and your password is not
about to expire, or simply because you auth'ed as the rootdn).

Did you read the man page and the draft that control is about? What are
you expecting it to do, otherwise?
