Authentik and Squid Proxy Redirection

[Gamechiefx]

Hello I am looking to setup squid proxy to redirect to authentik login page for authentication. I am unsure what mechanism i can use within authentik to redirect the user to the squid proxy once the user has authenticated successfully.

What would be the best approach to tackle this?

I don't think you can "redirect" proxy auth to an IdP.

Proxy auth support AFAIK 3 protocols: basic auth, NTLM and Kerberos.. there is no way to add some SAML/OpenID provider.. but often proxy application can use LDAP as authentication backend using basic auth on the client side.

but you can block the access to the squid port - if you are not logged in into authentik

If you have traefik installed you can intercept the access to the squid port because of tcp port - entryPoint

Here you are able to send automaticly an basic authentication - if you are logged in into authentic.
You have to use the Proxy Provider - not OAUTH nor others
