domaindir/ubuntu-symas-openldap repository overview

⁠Ubuntu Symas OpenLDAP

This repository provides a production-ready, containerized OpenLDAP server. It is built upon an Ubuntu 22.04 LTS (Jammy Jellyfish) base image, utilizes the enterprise-grade Symas OpenLDAP 2.6.13 binaries.

⁠🐧 Why Ubuntu 22.04 LTS Base?

While Symas provides their own minimal images, migrating to an Ubuntu 22.04 base image provides distinct administrative advantages:

• Security & Stability: Leveraging Canonical's Long Term Support (LTS) ensures predictable CVE patching for the OS layer until 2027.
• Troubleshooting: It provides a familiar, standard Linux environment (apt, systemd structures, standard glibc) making it drastically easier to debug network layers, certificate chains, and file permissions using standard Linux tooling.
• Compatibility: Native compatibility with standard monitoring, logging, and security agents that expect a standard Debian-based filesystem hierarchy.

⁠⚙️ Symas OpenLDAP Specifics

Symas OpenLDAP is a highly optimized, commercially backed build of the open-source LDAP directory server. Unlike standard Linux distribution packages (which often lag years behind), Symas provides the latest 2.6.x features, including the highly performant Memory-Mapped Database (back_mdb) and modern replication mechanisms.

⁠Symas Directory Structure

Because Symas compiles OpenLDAP independently to avoid conflicting with OS-level LDAP libraries, the paths differ significantly from standard Ubuntu /etc/ldap/ deployments.

When mounting volumes or editing configurations, you must use the following Symas-specific directories:

⁠🚀 Usage

Touchpoint for customized configuration: COPY slapd.conf /opt/symas/etc/openldap/slapd.conf

Running the Container:

docker run -d \
  --name ubuntu-symasldap-server \
  -p 389:389 \
  -v /path/to/your/slapd.conf:/opt/symas/etc/openldap/slapd.conf:ro \
  -v /path/to/your/data:/var/symas/openldap-data \
