When using a domain account to replace the default "[email protected]" account used by LCM for vCenter, the account does not show up under the infrastructure details of the automation nodes.
After updating the "Datacenters" account with a desired existing domain account, although the Locker in LCM shows that the "installervCenter" account is no longer in use, it still appears as the vCenter username/password account when navigating to Environments -> Select the datacenter -> Automation -> VMware Aria Automation Nodes -> expand a node: under the Infrastructure section the vCenter username/password isn't changed.
