Do Not Use VMCA, Provision with Custom Certificates
You can replace the existing VMCA-signed certificates with custom certificates. If you use that approach,
you are responsible for all certificate provisioning and monitoring.

Hybrid Deployment
You can have VMCA supply some of the certificates, but use custom certificates for other parts of your
infrastructure. For example, because solution user certificates are used only to authenticate to vCenter
Single Sign-On, consider having VMCA provision those certificates. Replace the machine SSL certificates
with custom certificates to secure all SSL traffic.
