An object identifier must describe every application and issuance policy that you define. The inclusion of an issuance policy object identifier in an issued certificate indicates that the certificate was issued in a manner that meets the issuance requirements associated with the issuance policy object.
Issuance or application policies by default are not critical. Making them critical can help ensure that a certificate is not used improperly. However, it also increases the likelihood that the certificate may not be compatible with all applications.
Membership in Domain Admins or Enterprise Admins, or equivalent, is the minimum required to complete this procedure. For more information, see Implement Role-Based Administration.
