Enroll for Certificates on Behalf of Other Clients

  • [アーティクル]

Applies To: Windows Server 2008

It is not always possible for users to enroll for a certificate on their own behalf. This can be the case for a user smart card certificate. By default, only domain administrators are granted permission to request a certificate on behalf of another user. However, a user other than a domain administrator can be granted permission to become an enrollment agent. A user becomes an enrollment agent by enrolling for an Enrollment Agent certificate.

Important

Once someone has an Enrollment Agent certificate, that person can enroll for a certificate and generate a smart card on behalf of anyone in the organization. The resulting smart card could then be used to log on to the network and impersonate the real user. Because of the powerful capability of the Enrollment Agent certificate, it is strongly recommended that your organization maintain very strong security policies over who has one.

Membership in the Users group and an Enrollment Agent certificate are the minimum requirements to complete this procedure. Review the details in "Additional considerations" in this topic.
