OpenLDAP Enable argon2 password hashing

[deeztek]

Name and Version

bitnami/openldap:2.6

What architecture are you using?

amd64

What steps will reproduce the bug?

Using the following docker-compose.yml file:

services:
  openldap:
    image: bitnami/openldap:latest
    ports:
      - '1389:1389'
      - '1636:1636'
    environment:
      - LDAP_ROOT=dc=domain,dc=local
      - LDAP_ADMIN_USERNAME=${LDAP_ADMIN_USERNAME}
      - LDAP_ADMIN_PASSWORD=${LDAP_ADMIN_PASSWORD}
      - LDAP_USERS=${LDAP_USERS}
      - LDAP_PASSWORDS=${LDAP_PASSWORDS}
      - LDAP_EXTRA_SCHEMAS=argon2
      - BITNAMI_DEBUG=true
    volumes:
      - openldap_data:/bitnami/openldap
      - ../config/openldap/custom/schema/argon2.ldif:/opt/bitnami/openldap/etc/schema/argon2.ldif

volumes:
  openldap_data:
    driver: local
    driver_opts:
      type: none
      o: bind
      device: /mnt/data/openldap

The contents of argon2.ldif are as follows:

dn: cn=module{1},cn=config
objectClass: olcModuleList
cn: module{1}
olcModulePath: /opt/bitnami/openldap/lib/openldap
olcModuleLoad: argon2.so

What is the expected behavior?

I expect the container to start.

What do you see instead?

The container fails to start with code 21 with the following logs:

Additional information

If I comment out both the LDAP_EXTRA_SCHEMAS and the argon.ldif volume, the container starts without any issues.
