When you replace the default certificates of the SDDC management products, you can manually generate certificate files that are signed by the intermediate Certificate Authority (CA). You have set up the Certificate Authority earlier on the Active Directory server.

Generate a CSR for the certificate that you want to replace. You generate the CSR on the machine where the certificate is installed.
