According to the VPNv2 CSP, these settings options are **Optional**. If you want your users to access on-premises resources, such as files on a network share, based on the credential of a certificate that was issued by an on-premises CA, and not the Cloud CA certificate, you add these settings to the VPNv2 profile. Alternatively, if you add the cloud root certs to the NTAuth store in on-prem AD, your user's cloud cert will chain and KDC will issue TGT and TGS tickets to them.

>[!NOTE]
>In Intune, the certificate selected in **Select a client certificate for client authentication** does not set any VPNv2 CSP nodes. It is simply a way to tie the VPN profile’s successful provisioning to the existence of a certificate. If you are enabling conditional access and using the Azure AD short-lived certificate for both VPN server authentication and domain resource authentication, do not select a certificate since the short-lived certificate is not a certificate that would be on the user’s device yet.
