Writing overlays

[Davor Ocelic <docelic@hcoop.net>]

Hello folks,

I was diving into OpenLDAP overlays code recently.
There's a lot of code in there even for seemingly simple
overlays.

I was wondering if you have some examples of overlay code
lying around, that don't do anything, but just hook into
the structure, receive data and pass data as-is?

That, or something like that, would be of great help for people
to create their own simple overlays, without having to learn
all ldap/openldap specifics and data structures first.

Thanks,
