    CAPolicy.inf file is only necessary when you need to make some pre-configuration which is not available in UI. If there is nothing special you want to pre-configure, then you don't need it. Most often reason when you need it -- when you want to include certificate policies extension in CA certificate. It is not configurable from UI.

    Hi,

    The CAPolicy.inf file defines the extensions, constraints, and other configuration settings that are applied to a root CA certificate and all certificates issued by the root CA. You can get more details about syntax and settings can be added on this file : prepare-the-capolicy-inf-file

    It's not necessary but recommended to be able to setup some settings not supported by UI and have a template of CA settings in order to simplify the CA installation and migration.

    Hello,

    Thank you so much for posting here.

    The CAPolicy.inf contains various settings that are used when installing the Active Directory Certification Service (ADCS) or when renewing the CA certificate.The CAPolicy.inf file is not required to install AD CS with the default settings, but in many cases the default settings are insufficient. The CAPolicy.inf can be used to configure CAs in these more complicated deployments.

    CAPolicy.inf is still necessary if you want to define some properties which are not configurable by using other means, like renewal settings, signature format for CA certificate and so on.

    Best regards,
    Hannah Xiong
