Account Used by Vsphere Web Client Plug-in Must Have a Role Within Enterprise Manager
The Veeam plug-in connects to Veeam Backup Enterprise Manager to verify the account. You can configure the Veeam plug-in to use the currently logged-in account or use a specific account for the connection. For details, see the procedure described in the user guide.
The account used must be assigned a security role — Portal Administrator or Portal User within Enterprise Manager. For more information, see Configuring Accounts and Roles.
