Docker LDAP Role

This Ansible role provides a streamlined implementation of an LDAP server with TLS support. It leverages Docker Compose to deploy a pre-configured OpenLDAP server and phpLDAPadmin for easy management.

🚀 Features

Secure LDAP with TLS:
- Automatically configures TLS certificates for secure communication.
- Provides configurable support for LDAPS on port 636.
phpLDAPadmin Integration:
- Includes a Dockerized phpLDAPadmin setup for easy user and group management.
Healthcheck Support:
- Ensures that the LDAP service is healthy and accessible using ldapsearch.
