Hi Luis,

I'm digging around in the Keystone code right now and helping answer your
questions is helping me learn the code base. Keep 'em coming!

Anyway, from what I can tell, you're correct that there's no general way to
get all of the tenants that a user belongs to in the current high level
API. However, there is already support for exactly this feature in the
lower level API. In [1] you'll see that the Driver object has the
method get_tenants_for_user. This method is implemented in all of the
backends in [2] so there's support for it everywhere, it just hasn't been
exposed in the high level API. Looking closer at [1] we see the comment,

# NOTE(termie): seven calls below should probably be exposed by the api
#               more clearly when the api redesign happens

which includes the method get_tenants_for_user. Looks like it's just a
matter of adding this method to one of the Routers to make it available in
the REST API.

My advice to you is to track down termie and find out what the story is
with the API redesign he mentions. Of course, you could always propose a
blueprint to [3] and make the method available yourself ;)

Hope this helps,
Everett
