Attaching the relevant slapd.conf
I don't think this is by any means relevant. I've run some basic checks, as I said, and nothing at the proxy side seems to be able to cause the error you report.
Either you provide an all-OpenLDAP setup, consisting of proxy, remote server and operation sequence that clearly shows the issue, so that we can reproduce and track it, or you should rather investigate what's happening between the proxy and the remote server, e.g. by providing a tcpdump of the communications resulting in the error you reported.
