I have never used Smallstep, but based on the documentation it looks like a native+id_token client. If you can get an error message or debug trace, you can sent it to me or open a GitHub issue and I will take a look at it 🙂

Thank you!

You can try VoidAuth, it is kinda similar to Authelia+lldap. I am the developer and I created it because I wasn’t satisfied with Authelia’s user management. If you decide you want to try it and run into any issues or questions I will try to help :)

VoidAuth is simpler to setup/use than Authentik for sure, but of course Authentik has more features. They both support proxy-auth, OIDC, and have user management UIs so in that way they are similar. I like VoidAuth for its simplicity but you can always run both and decide, if you have any questions about setup I will try to answer!

Let me know how it goes!
