I wouldn't consider OpenLDAP 2.2.13 as a reference in terms of
plausibility of returned error codes.  I'd note that since the late 2.3
the client library was badly broken in many aspects, mostly related to
concurrency and error handling.  In that specific case, I'd rather
inspect the logs (client, and server if anything gets to it at all), to
see what's causing an error, without relying too much on what the client
displays.  Actually, I'd rather upgrade to a stable, reliable and
supported version (2.3.41?  2.4.8?).
