It would be very strange if samba were reading /etc/group directly
anyway I think. Shouldn't it delicate to the nsswitch/getent() system?

Does kill -HUP make the problem go away? If so then there is a problem
in the systemd unit file or initscript (depending what smb has). Also if
the initscript does something different on reload than the native
systemd unit then, again, that is a bug.

Failing that, perhaps (assuming it's running) samba is using nscd (name
service cashing daemon) in which case you may need to do a "nscd -i
group" to invalidate the group cache.
