The error message is pretty explicit, your underlying filesystem doesn't 
understand posix ACLs. I think you have three choices here if you want 
an AD DC:

Search the internet for info on how to make Samba 4 provision on ZFS.

Use the ntvfs backend instead of s3fs, this is not something I would 
recommend, the ntvfs backend is not really maintained any more and could 
be removed at any time.

Use a different OS or filesystem that does understand posix ACLs

You can only provision as a DC, nothing else works, if you want to set 
up a standalone server, see the Samba wiki, but you will still have the 
posix ACLs problem, but there is a vfs to get round this.
