You must create a certificate template that can be used for issuing short-lived certificates, and you must specify which computers in the domain can request this type of certificate.
About this task
You can create more than one certificate template, but you can configure only one template to be used at any one time.
Verify that you have an enterprise CA to use for creating the template described in this procedure. See Set Up an Enterprise Certificate Authority.
Verify that you have prepared Active Directory for smart card authentication. For more information, see the View Installation document.
Create a security group in the domain and forest for the enrollment servers, and add the computer accounts of the enrollment servers to that group.
- On the machine that you are using for the certificate authority, log in to the operating system as an administrator and go to .
- Expand the tree in the left pane, right-click Certificate Templates and select Manage.

Change the template display name to True SSO.
Change the validity period to a period that is as long as a typical working day; that is, as long as he user is likely to remain logged into the system.
So that the user does not lose access to network resources while logged on, the validity period must be longer than the Kerberos TGT renewal time in the users domain.
(The default maximum lifetime of the ticket is 10 hours. To find the default domain policy, you can go to.)
Change the renewal period to 1 day.
