I've recently committed an overlay that implements the (expired) <draft-ietf-ldapext-ldapv3-dupent-08.txt> (ITS#6630); it's in contrib/slapd-modules/dupent/; configuration is pretty straightforward: load the module, and add

overlay dupent

in the database you want dupent to be enabled. I've only tested it as database specific, although it should also work as a global overlay.

Could anybody with access to a dupent-capable client please test it and report (through the ITS, in case)? I'm not 100% sure about the request/response encoding/decoding.

Thanks, p.
