OpenLDAP

Description

Unleash the potential of centralized identity management with OpenLDAP. This powerful directory service provides a robust platform for managing users, groups, and organizational units while ensuring secure, scalable, and efficient authentication and authorization.

Overview

Deploy OpenLDAP in a Docker environment with support for TLS-secured communication via an NGINX stream proxy. OpenLDAP offers advanced directory management capabilities, including flexible schema definitions, dynamic configuration overlays, and comprehensive query support with LDAP search utilities.

Cosmos

The diagram places OpenLDAP in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

Features

• Centralized Identity Management: Maintain a unified repository for all users and groups with robust organizational structures.

• Flexible Schema Support: Customize and extend directory schemas to meet diverse organizational requirements.

• Secure Communications: Enable TLS encryption for data in transit when accessed through an NGINX reverse proxy.

• Dynamic Configuration: Leverage runtime configuration overlays to adjust directory settings without downtime.

• Comprehensive Query Capabilities: Utilize LDAP search tools to efficiently query and manage directory data.

• High Performance and Scalability: Designed to handle large-scale deployments with rapid lookup and authentication response times.

Quick Setup

Development

Clone, set up the workstation, and deploy OpenLDAP onto the local stack:

git clone https://github.com/infinito-nexus/core.git
cd core
make onboard
make compose-deploy mode=reinstall apps=svc-db-openldap full_cycle=false

Production

Run the published image to provision the inventory and deploy OpenLDAP to a managed server (the mounted volume persists the inventory):

APP=svc-db-openldap
HOST=<your-server>
DOMAIN=<your-domain>
TLS_MODE=self_signed
SSH_PUBLIC_KEY="<your-ssh-public-key>"

docker run --rm -it \
  -v "$PWD/inventories:/etc/infinito.nexus/inventories" \
  -e APP="$APP" -e HOST="$HOST" -e DOMAIN="$DOMAIN" -e TLS_MODE="$TLS_MODE" -e SSH_PUBLIC_KEY="$SSH_PUBLIC_KEY" \
  ghcr.io/infinito-nexus/core/debian bash -c '
    INVENTORY=/etc/infinito.nexus/inventories/production
    infinito administration inventory provision "$INVENTORY" \
      --inventory-file "$INVENTORY/devices.yml" \
      --host "$HOST" \
      --include "$APP" \
      --vars "{\"TLS_MODE\": \"$TLS_MODE\", \"DOMAIN_PRIMARY\": \"$DOMAIN\", \"users\": {\"administrator\": {\"authorized_keys\": [\"$SSH_PUBLIC_KEY\"]}}}" &&
    infinito administration deploy dedicated "$INVENTORY/devices.yml" \
      --password-file "$INVENTORY/.password" \
      --diff -vv'

User Password Update Policy

By default, LDAP user passwords are updated on every deployment run.

To set a password only once (on initial user creation), set this flag per user:

users:
  alice:
    password: "..."
    password_update: false

With password_update: false, existing LDAP users keep their current password on later runs.
