SYNOPSIS
       shadowconfig on | off


DESCRIPTION
       shadowconfig  on  will  turn shadow passwords on; shadowconfig off will
       turn shadow passwords off. shadowconfig will print an error message and
       exit  with  a  nonzero code if it finds anything awry. If that happens,
       you should correct the error and run it again. Turning shadow passwords
       on when they are already on, or off when they are already off, is harm-
       less.


       Read /usr/share/doc/passwd/README.Debian for a  brief  introduction  to
       shadow passwords and related features.


       Note that turning shadow passwords off and on again will lose all pass-
       word aging information.
