I am investigating NS8 and wondering if it fits. My use case is as a NAS and email server for a number of users. From what I have read, if I want to us Samba shares I must use Samba AD for users. Does this then force my to use Active Directory on my LAN or can I still use the shares without requiring users to log on to the domain, i.e good old-fashioned samba file shares.
The client devices don’t need to be joined to the domain. They can browse the shares by using a previously created samba domain user like SAMBADOMAIN\username and password. Guest access isn’t implemented when in samba AD mode, see “FAQ - SambaWiki”
It’s possible to create mailboxes out of the AD users/groups but it’s also possible to define custom addresses, see Mail server — NS8 documentation
