NethServer is designed to serve a single organization with one or more domains (mail domains, web virtual hosts, etc…). It is not designed to manage multiple organizations like service providers do with multi-tenant applications.
Ok thanks!
Now I am using Zentyal for two Company on the same IT infrastructure using two separated VM.
I wonder if with Nethserver can use only one VM, but this isn’t a problem.
I am planning to change from Zentyal to Netthserver and can definitely use two VM, one per Company.
