When a host is added to a vCenter Server system, vCenter Server sends a Certificate Signing Request (CSR) for the host to VMCA. Most of the default values are well suited for many situations, but company-specific information can be changed.
You can change many of the default settings using the vSphere Client. Consider changing the organization, and location information. See Change Certificate Default Settings.
