keystone.identity.backends.base module¶

class keystone.identity.backends.base.IdentityDriverBase[source]¶

Bases: object

Interface description for an Identity driver.

The schema for users and groups is different depending on whether the driver is domain aware or not (as returned by self.is_domain_aware()).

If the driver is not domain aware:

• domain_id will be not be included in the user / group passed in to create_user / create_group

• the domain_id should not be returned in user / group refs. They’ll be overwritten.

The password_expires_at in the user schema is a read-only attribute, meaning that it is expected in the response, but not in the request.

User schema (if driver is domain aware):

type: object
properties:
    id:
        type: string
    name:
        type: string
    domain_id:
        type: string
    password:
        type: string
    password_expires_at:
        type: datetime
    enabled:
        type: boolean
    default_project_id:
        type: string
required: [id, name, domain_id, enabled]
additionalProperties: True

User schema (if driver is not domain aware):

type: object
properties:
    id:
        type: string
    name:
        type: string
    password:
        type: string
    password_expires_at:
        type: datetime
    enabled:
        type: boolean
    default_project_id:
        type: string
required: [id, name, enabled]
additionalProperties: True
# Note that domain_id is not allowed as a property

Group schema (if driver is domain aware):

type: object
properties:
    id:
        type: string
    name:
        type: string
    domain_id:
