- 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 theenforce_scopeflag so that you can get the benefits of new defaults andscope_typetogether. IfFalse, 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.
