Hmm, maybe I missed something in this discussion and about the usage of
client controls.

But I'd vote for another function which provides a complete set of
arguments for sending search requests. So if ldap_search_ext is
considered incomplete regarding alias dereferencing I'd vote for
introducing ldap_search_ext2 (or whatever name) with an additional argument.
