Many certificates can be distributed without the client even being aware that enrollment is taking place. These can include most types of certificates issued to computers and services, as well as many certificates issued to users.

To automatically enroll clients for certificates in a domain environment, you must:

  • Configure a certificate template with Autoenroll permissions. For more information, see Issuing Certificates Based on Certificate Templates (

  • Configure an autoenrollment policy for the domain.

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.
