When your OpenSSH server refuses to start with an invalid format error message when loading the host key, this weird reason might be the cause.

Update 2022-10-10: I published the code and added more container versions on dockerhub. Check the AnsibleDS post update.

Recently, I was massively bored over the weekend. So I started to redo my personal server setup.

I wanted to use an LDAP server for user management and got instantly confused over which one to choose. OpenLDAP is said to be fast and reliable, but the documentation is all over the place and usability is limited at best. 389 Directory Server has a better documentation but you need an extra management server and a console server. That was just too much hassle for me.

Luckily, there is ApacheDS. Sure, its written in Java but you only need to run one process and it comes with a fully fledged IDE.

Then again, there is no official docker container. So I made my own, together with a set of ansible scripts to deploy the container to my server. Enjoy!

Once, during a pandemic, I was bored. So I started playing around with some
stuff. This blog basically is a documentation of my learnings.

Have fun…
