I suppose. We're seeing eye-to-eye here, and using different words.
That was the use case I was envisioning as well.

Interesting way of describing it. I like it. How would we handle a
reset, though? We'd need some way to prune the pointer to the vouching
It would be nice if we could continue to cache access token info along
with the handle, and not have to re-enter it every time.
If we allow multiple vouching nodes, searching the tree to verify a
chain of awesome-ness back to Kelly can quickly turn into a hard
problem though. If one vouching is as good as three, I say we just
store one and keep the additional stuff as metadata.

Beats me. I've been futzing some with FreeIPA lately, and have found
it to be generally useful for getting LDAP up without much work.

I think that OpenLDAP would just be a storage mechanism for us. We'd
still have to write code to do our awesome-ness / vouching
verification though. At that point, I don't think it would be *that*
much more work to write a little data storage mechanism.
I'm thinking like JSON blobs in a Redis or flat text file.
