That's what I intend to do :)
dn_parent() has a side effect: it fails if the input dn
is a suffix of the supplied backend, if any; I'd like to
separate this behavior by defining two functions, one that
tests the dn against the backend suffixes and one that
climbs the subtree. I'm still trying to figure out if
in the first case it's better to do both operations in one
function or keep the two issues separated.
