User authentication failed


When adding an ESX server to Veeam Backup and Replication console and specifying SSH Connection Settings  the error message pops up: "Failed to login to "server_name" by SSH, port 22, user "user", elevateToRoot False, autoSudo False User authentication failed.


Account specified does not have root permissions on the source ESX host.


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.
