When users log in to a vCenter Server to manage roles and permissions within a VMware Cloud Foundation (VCF) 9.0 environment, they may notice several accounts that already have vSphere permissions assigned.
This might come as a surprise, especially if you do not recall creating these users, let alone granting them privileges within vCenter Server.
A large majority of the user accounts that you see are internal to the vCenter Server Appliance (VCSA) and represents the different application services running within the VCSA. There are also a handful of VCF accounts that are automatically created to enable communication between the various VCF components, but at the end of the day these are all service accounts that is either managed by vCenter Server or VCF.
With that said, it might be useful to understand which of these accounts are service accounts, so organizations can properly audit their environment for compliance and configuration management.
