As part of configuration, vMA creates a vi-user account with no password. However, you cannot use the vi-user account until you have specified a vi-user password.
The vi-user account has limited privileges on the target ESXi hosts and cannot run any commands that require sudo execution. You cannot use vi-user to run commands for Active Directory targets (ESXi or vCenter Server). To run commands for the Active Directory targets, use the vi-user or log in as an Active Directory user to vMA.
When you add ESXi target servers, vMA creates two users on each target:
When a user is logged in to vMA as vi-user, vMA uses that account on target ESXi hosts. The user can run only commands on target ESXi hosts that do not require administrative privileges.
