<PRE>'Twas brillig, and Richard Couture at 14/12/12 01:24 did gyre and gimble:
><i> While teaching a class in admin of GNU & Linux I noted that
</I>><i> systemctl reload smbd.service does NOT reread the /etc/group file.
</I>><i>
</I>><i> When adding a new user to a group which in smb.conf grants them access

</I>
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.
