I'd like to set up my identity and authentication service for my self hosted applications but it is not a beginner friendly subject. I'm aware of the various tools available; authentik, authelia, LLDAP, keycloak, etc and see lots of useful discussions on them which is great. But I can't seem to find a beginner friendly introduction to setting up one or more of these tools that helps me understand the core concepts at the same time. Does such a thing exist? I'd like to try out LLDAP and Authelia on my home lab and then possibly roll this out to my production services. But every tutorial I've come across seems to assume a fair amount of knowledge that I don't think I have. For instance if I deploy LLDAP what should I use as my base DN? And how can I seperate a homelab directory from a seperate production directory? Any pointers gratefully received.

This is a great collection of scripts to create containers hosting popular self hosted utilities in Proxmox.
