New published docker image for backend and ldap-auth daemons

[aptalca]

Hi, I'm with linuxserver.io and we are a volunteer group dedicated to creating and maintaining docker images for popular (mostly) open source apps.

We created a new docker image that combines the backend daemon and the ldap-auth daemon contained in this repo. As a docker container, it is extremely easy for a user to deploy, it is sandboxed from the system and all dependencies are satisfied within the image.

We also fixed the one current limitation of weak encryption in the cookies. Instead of base64, we implemented fernet encryption. Since both daemons run inside the same image, we are able to create a new fernet key during container creation or update, which is shared by the two daemons through this script.

Feel free to include a link in the readme of this repo. We are using it as a companion to our letsencrypt/nginx image (source here).

The docker image is hosted on docker hub, it is alpine based and therefore very lean, and it is multi-arch (x86_64, armhf and aarch64). The source is here.

We would also appreciate any feedback.

Thanks

Thank you for noticing. I'l take a look as time permits. Closing this now as not an issue.
