authentik VS authelia

Hey, for authentik this is actually something we're actively working on: https://github.com/goauthentik/authentik/pull/8330, and this will be included in our next feature release in April!

(Disclaimer, I am founder and CTO of authentik)

authentik CTO here; we’ll fix this in the next release (match-april), it should be possible in a non backwards incompatible way using the suggestion in this comment https://github.com/goauthentik/authentik/issues/6139#issueco... (which does call that solution a hack but I wouldn’t necessarily agree)

For anyone, considering authentik, I want to warn you by saying "here be dragons."

To start, I have protected 10+ services at any given time. Both in docker and k8s. Unless you enjoy configuring protection for each service independently, you'll have a bad time in authentik.

Authentik suffers from a debilitating bug[0] where when using a single config to protect all services on subdomains (i.e. app1.example.com, app2.example.com, etc.) your users will be randomly redirected to a different service when reauthenticating after the session expires.

I've been eyeing authentik[1] and authelia[2].

Authelia looks really good to me, but the fact that keycloak has connectors for angular and you need to setup oidc angular plugins with authelia for example made me a little bit wary. But I guess having a config for Keycloak makes it's easier to get started.

See here for the fix, which both implements the workaround suggested in the issue and also a much more standard-compliant method: https://github.com/goauthentik/authentik/pull/8471

Ask in the correct places for support: https://github.com/goauthentik/authentik/discussions and https://github.com/caddyserver/caddy/issues

Personally I went with Keycloak, because it's fairly well documented and also has Docker images available: https://www.keycloak.org/getting-started/getting-started-doc... although the fact that they want you to create an "optimized" image yourself and have a long build/setup process on startup instead is slightly annoying: https://www.keycloak.org/server/containers

Regardless, with something like mod_auth_openidc or another Relying Party implementation, all of the sudden authn/authz becomes easier to manage (you can literally get user information including roles in headers that are passed from your gateway/relying party to apps behind the reverse proxy), regardless of what you have actually running in your APIs: https://github.com/OpenIDC/mod_auth_openidc (there are other options, of course, but I went with that because I already use mod_md).

It's actually cool that there are plentiful options in the space, since OIDC is pretty complex in of itself and attempts at creating something pleasant to actually use are always welcome, I've also heard good things about Authentik: https://goauthentik.io/

For Authentik, it looks like they are not interested to write how to configure HAProxy with it https://github.com/goauthentik/authentik/issues/5768

It's me and two others though I'm definitely the most active. We put a lot of effort into security best practices and one of my co-developers is currently reviewing the 4.38.0 release. It's a fairly major release with a lot of important code paths that have been improved for the future.

Our official docs can be found at https://www.authelia.com and you can find docs for a particular PR in the relevant PR. We've also linked the pre-release docs in the pre-release discussions which can be found here: https://github.com/authelia/authelia/discussions/categories/...

> My only concern is that Authelia hasn't had a new release for more than a year, which raises security concerns.

I'm a bit concerned about that too. When setting it up, I found a lot of their docs on github mentioned they have `template` and `expand-env` "configuration filters", then it took me entirely too long to realize that while the 4.38 pre-release notes, posted in January 2023, say it's "just around the corner", it's still being worked on.

Having said that, there still seems to be somewhat active development. It may just be one person at this point.

That's not a new release of authelia. Authelia's releases are at https://github.com/authelia/authelia/releases

The updates to the AUR package were not about new releases since 2022:

If you are using HAProxy on PfSense/OPNSense, see my issue https://github.com/authelia/authelia/issues/2696

We used keycloak for openid identity provider as well. It is fine to setup keycloak once. But it is painful share the setup with other engineers.

For local development, we end up using dex (https://dexidp.io). When we need support group/role, we use dex and glauth(https://glauth.github.io). Both dex and glauth can be configured with yaml files. We just created a few yaml files and a docker compose file, every engineer can be brought up the whole environment in a few seconds.

Also https://www.authelia.com and https://github.com/goauthentik/authentik look pretty promising, if you need more advanced features from them.

https://github.com/lldap/lldap is a very simple and lightweight LDAP solution. Works flawless with https://www.authelia.com/

Ah yeah, so I guess it's been a while since I tried and I forgot where I got stuck last time. Authelia's config.yml is absolutely massive and I'm not sure which section of their guide I should be following. In The Docker Compose section, there's "Unbundled", "Lite", and "Local". I think I want to be running the "lite" bundle, but their example compose file has a ton of Traefik stuff in it. I know I wouldn't keep the Traefik services, but do I need either secure or public?
