Great questions.

Those users would start by obtaining a JWT. Then they would need to store
it somewhere between requests. Continuing the current pattern of storing a
file in ~/.pulp/ seems like a reasonable thing to do for a token. I imagine
that's what we'd have pulp-admin do, but maybe someone will suggest a
better idea.

I don't think we would attempt to namespace them. Multiple authorities
would be checked in a configured order, and the first one to allow
authentication would win. If a deployer of pulp has multiple authorities
with overlapping users, I think it's up to them to manage the priority of
each authority. This approach would allow an organization to migrate from
one authority to another without having to worry about updating prefixes or
namespaces in pulp.

I agree that auto-creation of users and groups is a feature that could
easily wait for 3.1+. In the spirit of starting from a minimum viable
product, I think we should do just the essentials until we at least have a
working alpha of 3.0. Then we can prioritize additional work. From that
point, we'll probably want to focus our 3.0 work on making
backwards-incompatible changes while we have the chance.

Heck ya! As much of this as we can do in that project, we should. I'm not
sure if having a custom user model might make it more complicated to do
this generically, but we'll certainly try.
