But if you do this, remember,
-m Leave the environment unmodified. The invoked shell is your lo-
gin shell, and no directory changes are made. As a security pre-
caution, if the target user's shell is a non-standard shell (as
defined by getusershell(3)) and the caller's real uid is non-ze-
ro, su will fail.
You have to add '/sbin/nologin' to /etc/shells.
