Hello,

I am trying to use Argon2 or PBKDF2_SHA256 as a secure password hashing function.
Since two weeks I am trying to get this to work with reading a lot of information on the internet and I just cannot get it to work.

I am using Ubuntu 20.04 LTS, installed with slapd, ldap-utils, argon2 and trying to set it in the cn=config Frontend setting.

@(#) $OpenLDAP: slapd  (Ubuntu) (May 12 2022 13:11:05) $
        Debian OpenLDAP Maintainers <pkg-openldap-devel@lists.alioth.debian.org>

This is the version that is installed from Slapd and when I try to set pw-argon2, {ARGON2}, pw-argon2.so... I tried a lot and it tells me no hash found. If I try {MD5} it works without problems.

As there is no other secure usable password hashing installed the LDAP Server is right now insecure and I cannot move it to production

Please does someone has any idea?

Many kind regards,
Lukas
