You can regenerate the VMCA root certificate, and replace the local machine SSL certificate and the local solution user certificates with VMCA-signed certificates. When multiple vCenter Server instances are connected in Enhanced Linked Mode configuration, you must replace certificates on each vCenter Server.
When you replace the existing machine SSL certificate with a new VMCA-signed certificate, vSphere Certificate Manager prompts you for information and enters all values, except for the password and the IP address of the vCenter Server, into the certool.cfg file.
- Password for [email protected]
- Two-letter country code
- Company name
- Organization name
- Organization unit
- State
- Locality
- IP address (optional)
- Host name, that is, the fully qualified domain name of the machine for which you want to replace the certificate. If the host name does not match the FQDN, certificate replacement does not complete correctly and your environment might end up in an unstable state.
- IP address of vCenter Server.
- VMCA name, that is, the fully qualified domain name of the machine on which the certificate configuration is running.
Note: As of vSphere 7.0 Update 3o, the OU (organizationalUnitName) field is no longer mandatory.
Prerequisites
You must know the following information when you run vSphere Certificate Manager with this option.
- Password for [email protected].
- The FQDN of the machine for which you want to generate a new VMCA-signed certificate. All other properties default to the predefined values but can be changed.
