I can't quite understand groups.
For example, lets say if I add the following into my
valid users = @users
Must the group
users exist on my system or is a samba group itself?
And if the former, how can I create this group. via
groupadd -r users?
After that, only those valid users in that group can browse files, right?
When I log in now as
root to list all groups via
groups, it just says
root, nothing more, but I need to know all groups.
