RE: OpenLDAP Dynamic Backends

["Howard Chu" <hyc@highlandsun.com>]

You don't need to change anything in slapd/result.c, you can use callbacks to
invoke your code. If the dynamic data resides in completely separate objects
you may be able to just use subordinate backends to assemble the search
results. Otherwise, you can still use the code in slapd/backglue.c to model
your own backend with callbacks.

I need OpenLDAP to serve data that is partially static and partially
generated on the fly.  Because the number of dynamically generated fields is
very small, it seems to make sense to implement some kind of proxy backend
that handles those  few objects and passes the rest of the searches off to a
std backend.

I think that the correct way to do this is to generate the field after the
other backend has failed it's search.  It doesn't make sense to scan every
search for a certain substring.  Does it seem sensible for me to drop code in
slapd/result.c that calls my back-dynamic module?

thanks
