class swh.deposit.auth.KeycloakBasicAuthentication[source]

Bases: rest_framework.authentication.BasicAuthentication

Keycloack authentication against username/password.

Deposit users will continue sending Basic authentication queries to the deposit server. Transparently, the deposit server will stop authenticate itself the users. It will delegate the authentication queries to the keycloak instance.

Technically, reuses rest_framework.BasicAuthentication and overrides the func:authenticate_credentials method to discuss with keycloak.

As an implementation detail, this also uses the django cache mechanism to avoid too many authentication request to keycloak.

property client
get_user(user_id: str) Optional[swh.auth.django.models.OIDCUser][source]

Retrieve user from cache if any.

authenticate_credentials(user_id, password, request)[source]
