If I log in as root on the console, through telnet, and through ssh and
noauth the three, would these be in the same login group? In my tests,
it seemed that one rmauthed oysteivi logged in through telnet could not
kill the processes of another rmauthed oysteivi. (two nousers with
different login ids, no?)
If not, when you log in, start bind, log out, log in, stop bind, start
bind, how can you make sure it gets access to the same files? Wouldn't
you have to preallocate a login id for bind then, effectively doing the
same as having a dedicated named user?
