Only if the API is not subject to continous changes. We have to
ask that on OpenLDAP-software mailing list. I suspect the answer
of Kurt is "don't rely on that API".

Hmm, if someone is digging into ber.h we're very near to an
approach where we re-implement parts of the LDAP protocol engine.

There's something called "A Layman's Introduction to BER, DER and
ASN.1" on RSA's web site.

Hmm, then it does not make sense to me. Also I believe that we can
come up with a better Pythonic design if we define thoroughly
thought Python classes.
