Self-hosted SSO (midwest.social)

What are you folks using for self-hosted single sign-on?

I have my little LDAP server (lldap is fan-fucking-tastic -- far easier to work with than OpenLDAP, which gave me nothing but heartburn). Some applications can be configured to work with it directly; several don't have LDAP account support. And, ultimately, it'd be nice to have SSO - having the same password everywhere if great, but having to sign in only once (per day or week, or whatever) would be even nicer.

There are several self-hosted Auth* projects; which is the simplest and easiest? I'd really just like a basic start-it-up, point it at my LDAP server, and go. Fine grained ACLs and RBAC support is nice and all, but simplicity is trump in my case. Configuring these systems is, IME, a complex process, with no small numbers of dials to turn.

A half dozen users, and probably only two groups: admin, and everyone else. I don't need fancy. OSS, of course. Is there any of these projects that fit that bill? It would seem to be a common use case for self-hosters, who don't need all the bells and whistles of enterprise-grade solutions.

LLDAP + Authelia

I actually moved from Authentik to Authelia because it was easier for me to add a couple of lines to a yaml than to navigate Authentik's web ui. Authentik is more feature-full but I'm only running SSO for myself and a couple of others at home.

Yeah, that sounds ideal. I'd prefer editing a file than administering through a web page.

I'm checking Authelia right now.

SSO is part, but not all, of the picture. There's also multi-system passwords, for things like sudo, and non-web service authentication; most of the stuff like OAUTH is really hacky to make work outside of web environments.

I've considered Vault for some of the inter-service authentication, but there's not broad support built into services and it's yet another thing to mess with.

LDAP forms a good base for most use cases, and so keeping it as the source of truth is important for me. And then, as few other layers on top to get SSO. Authelia is looking like the best solution.
