Here my personal working docker-compose.yml:

version: '3.3'

services:
  lldap:
    image: nitnelave/lldap:stable
    container_name: lldap
    volumes:
      - "./lldap:/data" # For the config file, server private key and the sqlite database.
    environment:
      - LLDAP_JWT_SECRET=CHANGEME

Describe alternatives you've considered
Setting up an OpenLDAP is a nightmare. FreeIPA can work, but it's a bit overkill. Kanidm/KeyCloak don't offer a writeable LDAP layer.

Additional context
It comes with a snappy web interface and is lightweight in resources, and easy to install. Lots of examples on how to configure other services to interface with it.
