How do I make a HTTP GET request to a Kerberos protected site using Elixir (or Erlang)?

Question

Essentially I would like to do this ( Python ) but in Elixir:

import requests
from requests_kerberos import HTTPKerberosAuth, OPTIONAL
kerberos_auth = HTTPKerberosAuth(mutual_authentication=OPTIONAL)
r = requests.get("http://example.org", auth=kerberos_auth)

I know I can just do :

HTTPotion.get "http://example.org"

But I cannot find an example (with HTTPotion or any other Elixir library) that supports kerberos negotiation for Elixir (or Erlang)

Is crafting a command line call of curl the only path forward?

This library claims to support SPNEGO, which is what is required for kerberos based http. I have no idea how well it actually works.

It's pretty old, but SPNEGO and kerberos API's haven't changed much in the last 7 years.

As a general rule, unless the underlying library driving the web connection is libcurl, SPNEGO is not well supported in most languages. Java and C are pretty much it when it comes to robust working kerberos implementations; the easier it is for the language to interact with those libraries, the more likely kerberos support will be available.
