Take a look at https://bugzilla.redhat.com/show_bug.cgi?id=1648399 for 
the reason.

You are setting up a standalone server so you may need to run:

net -s /dev/null groupmap add sid=S-1-5-32-546 unixgroup=nobody type=builtin

If so, remove it, it isn't required for a standalone server and it 
interferes with smbd. This is a known bug that has been fixed at 4.9.5

the printer working, I'll create a new thread.
