I need to update one of my Active Directory Certificate Services (ADCS) certificate templates from schema v2 to v3, to support KSP providers. It seems that I can only do this by cloning the template (only then I get an option to select KSP).
Is it possible to do it in situ? If so, how?
You have to duplicate existing certificate template and configure as per your needs. This is the only supported way to get V2/V3/V4 template schema version.
