Bases: object

abstract create_implied_role(prior_role_id, implied_role_id)[source]

abstract delete_role(role_id)[source]

Delete an existing role.

Raises:

keystone.exception.RoleNotFound – If the role doesn’t exist.

abstract get_implied_role(prior_role_id, implied_role_id)[source]

Get a role inference rule.

Raises:

keystone.exception.ImpliedRoleNotFound – If the implied role doesn’t exist.

abstract get_role(role_id)[source]

Get a role by ID.

Returns:

role_ref

keystone.exception.RoleNotFound – If the role doesn’t exist.

abstract list_implied_roles(prior_role_id)[source]

abstract list_role_inference_rules()[source]

List all the rules used to imply one role from another.

abstract list_roles(hints)[source]

List roles in the system.
