There may be times when you want to modify the properties of a type of certificate that has already been issued to clients. You can do this by creating an updated certificate template for that certificate purpose and specifying that you want subjects of certificates based on the old template to obtain new certificates based on the new template. This procedure forces subjects to obtain a new certificate before the renewal date specified in the original certificate template.
Membership in Domain Admins, or equivalent, is the minimum required to complete this procedure. For more information, see Implement Role-Based Administration.
