Hello,
In this case you user as you can see is not authorized to do activity on the appliance vCenter, the administrator group are the administrator of the vsphere.local SSO not the Appliance itself.
Could be that if you put that user in this group:
SystemConfiguration.BashShellAdministrators
you should be able to use that user in bash
let me know
Kudos if it was helpful
