|  | features: | 
|  | - | | 
|  | Add a new config setting ``immutable_user_source`` in the | 
|  | ``[identity-feature-enabled]`` group that defaults to false. | 
|  | This setting, combined with the usage of the ``@testtools.skipIf()`` | 
|  | decorator, will allow tests that require user creation, deletion, | 
|  | or modification to skip instead of failing in environments that | 
|  | are LDAP-backed. In such environments, the user source is read-only, | 
|  | so this feature flag is needed to allow such tests to gracefully skip | 
|  | without having to blacklist them. |
