NAME
shadowconfig - toggle shadow passwords on and off
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
harmless.
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
password aging information.
