Roles should be inherited down the tree, and ownship should be resolved
up the tree:
I started a Blueprint to handle the policy file side of this mechanism,
but the same general rule can work for a larger class of resources:
https://blueprints.launchpad.net/keystone/+spec/policy-for-endpoint
This is parallel to, but separate from, the HMT discussion. I think,
though, that both mechanisms should follow the same rules.

Ofcourse, the difference here is (compared to what i put in the wiki page) that, only roles at each level (if different) needs to be added to scope and no need of adding the project name and role individually. Is this ok, considering the fact that the more deeper in the hierarchy the user is getting authenticated, the more time needed to parse upto the level 1.

>> I think you can simplify the roles in the hierarchical model by only passing the roles for the authenticated project and above. All roles are then inherited down. This means it isn?t necessary to pass a scope along with each role. The scope is just passed once with the token and the project-admin role (for example) would be checking to see that the user has the project-admin role and that the project_id prefix matches.

>> There is only one case that this doesn?t handle, and that is when the user has one role (say member) in ProjA and project-admin in ProjA2. If the user is authenticated to ProjA, he can?t do project-adminy stuff for ProjA2 without reauthenticating. I think this is a reasonable sacrifice considering how much easier it would be to just pass the parent roles instead of going through all of the children.
