OpenLDAP Docker Image for testing

This Docker image provides an OpenLDAP Server for testing LDAP applications, i.e. unit tests. The server is initialized with the example domain with data from the Futurama Wiki.

Parts of the image are based on the work from Nick Stenning docker-slapd and Bertrand Gouny docker-openldap.

The Flask extension flask-ldapconn use this image for unit tests.


  • Initialized with data from Futurama
  • Support for LDAP over TLS (STARTTLS) using a self-signed cert, or valid certificates (LetsEncrypt, etc)
  • memberOf overlay support
  • MS-AD style groups support
  • Supports Forced STARTTLS
  • Supports custom domain and custom directory structure

JAAS configuration

In case you want to use this OpenLDAP server for testing with a Java-based application using JAAS and the LdapLoginModule, here's a working configuration file you can use to connect.

other { REQUIRED

This config uses the admin credentials to connect to the OpenLDAP server and to submit the search query for the user that enters their credentials. As username the uid attribute of each entry is used.
