By default, the Use service console connection to this server check box is selected. Enter the user name "root" and password to login to the service console of the server under the SSH connection tab.
If you choose to use a non-root account that does not have sudo permissions on the ESX server, you can use the Non-root account options section to grant sudo rights to this account.
Select the Elevate account to root check box to provide a non-root user with access to the added server.
You can add the account to sudoers file automatically by selecting the Add account to the sudoers file automatically check box.
If you do not select this option, you will have to manually add the user to the sudoers file.
