Bitnami-compatible OpenLDAP image

A drop-in replacement for the Bitnami OpenLDAP image, built entirely from open-source components.

Key differences from the official Bitnami image:

• OpenLDAP is compiled directly from the upstream sources (no Bitnami-built tarball)
• Base image is debian:13-slim instead of Bitnami's minideb

Quick start

# docker-compose.yml
services:
  openldap:
    image: ghcr.io/ripolin/openldap:latest
    ports:
      - '1389:1389'
      - '1636:1636'
    environment:
      - LDAP_ADMIN_USERNAME=admin
      - LDAP_ADMIN_PASSWORD=adminpassword
      - LDAP_USERS=user01,user02
      - LDAP_PASSWORDS=password1,password2
    volumes:
      - openldap_data:/bitnami/openldap

volumes:
  openldap_data:

Available tags

Images are published to ghcr.io/ripolin/openldap for linux/amd64 and linux/arm64.

Compiled modules

In addition to the standard overlays, the following contrib modules are included:

Module	Description

Configuration

This image is fully compatible with the Bitnami OpenLDAP image configuration. All environment variables, volumes, and entrypoint scripts behave identically.
