enforce_new_defaults¶

Type: boolean
Default: False

This option controls whether or not to use old deprecated defaults when evaluating policies. If True, the old deprecated defaults are not going to be evaluated. This means if any existing token is allowed for old defaults but is disallowed for new defaults, it will be disallowed. It is encouraged to enable this flag along with the enforce_scope flag so that you can get the benefits of new defaults and scope_type together. If False, the deprecated policy check string is logically OR’d with the new policy check string, allowing for a graceful upgrade experience between releases with new policies, which is the default behavior.

policy_file¶
