authentik VS vouch-proxy

If you're looking for a system that has more features, is user friendly, a nice admin ui and easy deployments compared to Keycloak. Please give https://goauthentik.io/ a shot. Not affiliated in any way, just a very happy user.

It has

-an admin UI

- Supports (LDAP, SAML, OAUTH, social logins)

- MFA, Passkeys

- Application access based on user groups etc

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)

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

I've been searching around for a while now, and struggling with getting Authentik setup on my NAS. I'd like to deploy via Portainer, but getting lost in the documentation just to deploy.

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/

Hello ! I am hosting a server under NixOS with multiple services, and to simply the identity management, I use authentik (https://goauthentik.io/) which can be compared to keycloak. Everything works fine until I try to enable mastodon to host an instance : authentik returns an error 400 and nothing changes this but disabling mastodon. Does anyone have an idea of what could be the cause of this ?

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

Look into vouch proxy

Vouch proxy is designed for this usage: https://github.com/vouch/vouch-proxy I don't think there are any nice UIs to configure it though so you'll need to be familiar with running it yourself.

Not sure this is a "best practice", but it lets me keep control of the Ingress resources inside their YAML configs. I've also layered Vouch Proxy into the ingress configurations to require SSO/MFA auth to access the resources behind the Ingress. Cloudflare has the ability to do this, but I found it cumbersome to keep track of the configs outside the K8s cluster.

I've used vouch proxy for my own stuff previously, before more recently moving to Cloudflare Access. vouch can be slightly janky at times to get working right, but once set up, it's been solid.

For example: nginx -> Vouch proxy -> KeyCloak -> Jellyfin

While this works, we were hoping to make access a bit easier with say an OpenID Connect SSO and reverse-proxy solution. I've seen Vouch Proxy, https://github.com/vouch/vouch-proxy which is really just SSO on top of nginx, but I'm wondering if there's a simpler way to do this.

You seem to be quite knowledgeable and a minimal provider with just the bare minimum would suffice for you. Have a look at Vouch Proxy, it does one thing and it does it well.
