--- Comment #2 from Michael Ströder michael@stroeder.com --- Stuffing the Argon2 parameters into moduleload directive seems wrong to me.
IMO they should be defined by a config directive similar to password-crypt-salt-format or cn=config attribute olcPasswordCryptSaltFormat.
Suggested naming:
slapd.conf: password-argon2-params
cn=config: olcPasswordArgon2Params
Syntax of the config values could be the same like in moduleload directive.
