OK. It's not the file itself, more what I'm passing to the operating system. I'm using sssd, which seems to copy username to gecos and have / as the default home directory even if those attributes are not populated in AD. It will however allow me to leave login shell blank. getent then gives me this: cifsuser:*:3000020:20513:cifsuser:/: which gives the correct number of ":". I'm not sure whether it's sssd or AD which decides on the defaults. Anyway, a bit better.
A blank login shell is interpreted as "/bin/sh". If logins are never to be allowed for this user, I would typically set the shell to "/noshell", which does not have a special meaning, but will deny login as long as "/noshell" does not exist in the file system. Any non-existent file path would do the same thing.
Please see "man nologin" for the 'polite' way to do this :-)
Hi I can't get it polite: hh16:/tmo # nologin This account is currently not available. works OK but it's not polite: hh16:/tmp # su cifsuser Password: su: /noshell: No such file or directory
Help me here; why is a FAIL polite but a correct execution and sensible message that says nothing about the internals not polite. "Polite" as in 'not abusing the system by relying on a FAIL' The 'nologin' will work even if some idiot sysadmin who isn't in on it were to create "/noshell" thinking it a form of ".nologin" as has been used on some versions of UNIX in the past. Perhaps things would have been clearer if I had said "robust" rather than "polite", but I think that making an ABEND do the job of 'nologin' is a klude and unreliable. -- How long did the whining go on when KDE2 went on KDE3?
