Deleting a Certificate Template
Deleting a template deletes all signed certificates and pending requests for the template. Before deleting a certificate template, ensure that a certificate with that name is not in use by a server. If a certificate with the same name as the certificate template is in use by a server, the delete operation returns an “Invalid input” error.
To delete an unused certificate template:
Click the Security icon in the left tree menu.
Click the Certificate Templates icon on the left tree menu.
Click the certificate template name on the left tree menu.
On the Certificate Template page, click Delete.
In the confirmation page, select OK.
