Simple guide to self hosted authentication? (lemmy.world)

submitted 1 year ago by [email protected] to c/[email protected]

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.

I don't have a simple guide, but it's probably a good idea to reduce the number of moving parts if you're trying to keep stuff simple. So pick something that has all the features in-one (user management, authentication, authorization, ...). They might not be the best at ever single thing (they almost certainly won't), but doing it all usually means that it's easier to configure and you don't need to wire multiple things together.

I've recently moved from Authelia to Authentik due to some features that I was missing/wishing for, but between those two I'd definitely say Authenlia is easier to get running initially (and you don't need external LDAP for it, as others have mentioned).

You'll probably still need a proxy that can do proxy auth because not all services can do OICD/OAuth2. I'm using Traefik, but heard that Caddy is easier to set up initially (can't compare myself).
