EFS and Autoenrollment
EFS always attempts to enroll for the Basic EFS template by default. The EFS
component driver generates an autoenrollment request that autoenrollment
tries to fulfill. For customers who want to ensure that a specific template
is used for EFS (such as to include key archival), the new template should
supersede the Basic EFS template. The Basic EFS template should also be
removed from any Enterprise CA. This will ensure that autoenrollment will
not attempt enrollment for the Basic EFS template any more. For customers
who wish to replace the Basic EFS template with a certificate and key that
is archived through the Windows Server 2003, Enterprise Edition CA, the
proper procedure is to supersede the Basic EFS template with a new version 2
certificate template.
