Auth context is essentially the user credential used for policy enforcement.

It is a dictionary with the following attributes:
|
|
|
|
* ``user_id``: user ID of the principal
|
|
* ``project_id`` (optional): project ID of the scoped project if auth is
|
|
project-scoped

* ``domain_id`` (optional): domain ID of the scoped domain if auth is
|
|
domain-scoped
|
|
* ``roles`` (optional): list of role names for the given scope
|
|
* ``group_ids``: list of group IDs for which the API user has membership
