If IPA can be made to work, then I'm all for it. I'd like something we
can use that won't require a ton of custom patching in the future.

We've not put anything together officially, but we do have a basic list.

Auth primarily needs to function for git, koji, http, and local auth
(for the projects who require a vm). Further integration like the forums
or bugs is a bonus, but not a deal breaker.

Users need to be able to maintain their own accounts, to include
generating an ssl cert for koji, resetting password, uploading ssh keys,
etc. If these steps require intervention from someone on the project,
then it fails. SIG leaders should be able to manage their own groups, so
we'd need tiered permissioning. Project folks add sig leaders, sig
leaders can add sig members etc.

Currently the only two auth mechanisms that seem to cover both aspects
of this are FAS and IPA. Each seem to have a few drawbacks.


KB/Fabian, shall we add a trello card with more formal requirements?
Then we can do a head-to-head to see what works.
I'm entirely fine with having a shoot-out between them. If Howard wants
to take on setting up an IPA instance in a vm, I believe Karsten is
working on a FAS test instance.
