This is a simple HTTP server which allows you to authenticate against ldap with a HTTP GET request. This daemon is designed to run behind a reverse proxy (haproxy, nginx, apache2, ...).
To authenticate against this daemon you only need to fire a GET request with base64 encoded Authentication HTTP header.

git clone https://github.com/g0dsCookie/ldapauthd.git
cd ldapauthd
pip install -r requirements.txt
Now you may run with ./ldapauthd.py
but I highly recommend reading Configuration.
Docker image g0dscookie/ldapauthd is available. See docker-compose.yml for configuration and usage of this container.
