<sect2><title>Configuring Shadow Password Suite</title>
<para>
This package contains the utilities to modify user's passwords, add new
users/groups, delete users/groups and more. I'm not going to explain
what 'password shadowing' means. All about that can be read in the doc/HOWTO
file within the unpacked shadow password suite's source tree. There's one
thing a user should keep in mind, if he decides to use shadow support, that
programs that need to verify passwords (examples are xdm, ftp daemons,
pop3 daemons, etc) need to be 'shadow-compliant', eg. they need to
be able to work with shadow'ed passwords.
</para>
<para>
Shadow'ed passwords are not enabled by default. Simply installing the
shadow password suite does not enable shadow'ed passwords.
</para>
<para>
Now is a very good moment to read chapter 5 of the doc/HOWTO file. It
describes
how to enable shadow'ed passwords, how to test whether shadowing
works and if not, how to disable it again.
</para>
<para>
The documentation mentions something about the creation of npasswd and
nshadow after pwconv is run. This is an error in the documentation.
Those two files will not be created. After pwconv is run, /etc/passwd
will no longer contain the passwords and /etc/shadow will. A user doesn't
need to rename the npasswd and nshadow files himself.
