SHADOWCONFIG(8) System Manager's Manual SHADOWCONFIG(8)
shadowconfig - toggle shadow passwords on and off
shadowconfig on | off
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 hap-
pens, 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 pass-
word aging information.
