There's a document available; see servers/slapd/overlays/slapover.txt
the rest is about ccoding by example, i.e. look at available overlays and
learn from that.  In my opinion (I'm regularly using overlays and I coded
a few) one essentially requires a good knowledge of OpenLDAP's slapd
internals, because there's no clear definition of an internal API as a
common, neutral interface access point to the internals.  We are evolving
in that direction, and the (*)(op, rs) handle/callback mechanism is a clear
example.  If you're considering to develop your own overlay for relatively
straightforward purposes, feel free to ask questions or submit pieces of
code; if you are more oriented towards improving the overlay mechanism,
then you should definitely move to -devel as a more appropriate forum.

Ciao, p.
