LDAP is LDAP. It's a protocol, not a schema definition. If the LDAP
libraries don't ask the directory service about the schema and the
properties of the classes and objects, but just assume that they have
some predefined sturcture, that's not the fault of the directory
service.

I'd be asking this in one of the open source newsgroups, not here. An
LDAP query should be the same no matter what's at the other end -- if
the query's constructed the right way and the software asking the
question is capable of understanding the information returned.

Simple queries shouldn't present much of a problem, but queries for
group information might cause you problems. Authentication should be
workable too, but probably not without work.

You might find it easier to run an OpenLDAP server and just dump the
stuff from the AD into it periodically. Or you can invest in a
directory synchronization software.
