that's sort of the idea. Actually, I can already achieve multi-tenancy with the current version of Veeam ONE because when one of my customers logs into Business View, Monitor or Reporter, they can only have access to their infrastructure according to the permissions in vCenter. Although there are a few things that could be improved, that option is available now.
The idea of this particular feature is that I'd like to provide access to Veeam ONE to customers as an add-on service. At the moment, if they have access to vCenter, there's nothing I can do to stop them from accessing Veeam ONE because it authenticates with vCenter so the same credentials will work. However, if we can restrict access to Veeam ONE by using a security group in AD (or any other suitable method), then I can choose if they will have access to all the reporting and monitoring tools in addition to their vCenter access.
