So, would it be possible to have a lazy-load of global config (so that the module gets loaded) followed by a strict reload of global config as a way around this?
Operator error on my part it seems. ;) The olcPasswordHash bit has to go under cn=frontend,cn=config rather than at cn=config, as noted in the man page, which I missed.
