🛡️ uSentry - Identity & Access Management

Submitted ⁨⁨1⁩ ⁨day⁩ ago⁩ by ⁨TCB13@lemmy.world⁩ to ⁨selfhosted@lemmy.world⁩

uSentry is a lightweight, self-hosted Identity and Access Management (IAM) and Single Sign-On (SSO) solution designed for homelab and small-scale environments.

⚡ A single PHP file. < 400 lines of code. No database. No background processes. No cloud. Just works. ⚡

Most IAM and SSO solutions require databases, certificates and background services baked into a dozen containers. This is all fine but also also overkill for homelabs and impossible for low-power ARM devices. uSentry is different, it isn’t pretty but it sucks less for a lot of use cases.

Enjoy!

I love the simplicity of this, I really do, but I don’t consider this SSO. It may be if you’re a single user, but even then, many things I’m hosting have their own authentication layer and allow offloading only to some oidc-/oauth-provider.

  In the simplest form it might be SSO. It does support multiple users and if you look for instance at the filebrowser example I’m passing the user from to filebrowser. But yes, this is very simple, very crude and exactly what a lot of people need.

I’m torn between this being fucking genius, and a terrible idea all at once.

  Well, me too. But frankly Keycloak, Authelia do too much, require too much and aren’t suitable at all for SBCs and small scale stuff.

    I respect it.

  I didn’t test, but should be possible with forward_auth (caddyserver.com/docs/caddyfile/…/forward_auth)

I have been constantly asking myself why there isn’t something like this, and just wondering if maybe I was missing something about the seeming immense complexity of doing this on a small scale.

Now there is something like this.

  Well, it isn’t pretty, but gets the job done.
  
  The thing with PHP in this case is that I was already serving a ton of simple websites / small apps like freshrss that use PHP and by making this tool in PHP it means I don’t need yet another process running and wasting resources, can just re-use the existing php-fpm for this.
  
  For what’s worth PHP is better than it looks, and my implementation is very crude, but also small and auditable and contained to a single file. :)

Fun little project but I think auth_basic would be perfectly fine instead.

  Hmm… some people are going to say that basic auth would be insecure, I’m not going to be there because in this particular case it’s about the same thing.
  
  However, this might be easier to configure and manage permissions than basic auth. Also this works cross-domain and basic auth will require full re-auth for every domain. Another obvious advantage is that at some point I plan to integrate 2FA.

You also could go freeipa or Samba AD

I feel like committing secrets to a config file instead of .env is a terrible idea. Thats being said this is really useful I’m sure.

source
- Xanza@lemm.ee ⁨14⁩ ⁨hours⁩ ago
  The entire point of .env files are to separate secrets from code. Its specifically the usage for which they were created.

    Yes?
    
    Are we misunderstanding each other?

  I get the point, but don’t forget those “secrets” are SHA256 hashes. Not really reversible.

    The issue isn’t that. The issue is its a config folder and a lot of people back their configs up to things like github.
