= Authorization Policy
In previous versions of Keycloak when the last member of a User, Group or Client policy was deleted then that policy would also be deleted. Unfortunately this could lead to an escalation of privileges if the policy was used in an aggregate policy. To avoid privilege escalation the effect policies are no longer deleted and an administrator will need to update those policies.
