<sect2><title>Configuring Shadow</title>
<para>This package contains utilities to modify users' passwords, add
or delete users and groups, and the like. We're not going to explain what
'password shadowing' means. A full explanation can be found in the
<filename>doc/HOWTO</filename>
file within the unpacked Shadow source tree. There's one
thing to keep in mind if you decide to use Shadow support: programs that
need to verify passwords (for example xdm, ftp daemons, pop3 daemons) need
to be 'shadow-compliant', that is they need to be able to work with
shadowed passwords.</para>
<para>To enable shadowed passwords, run the following command:</para>
<screen><userinput>/usr/sbin/pwconv</userinput></screen>
<para>And to enable shadowed group passwords, run the following
command:</para>
<screen><userinput>/usr/sbin/grpconv</userinput></screen>
<para>Under normal circumstances, you won't have created any passwords yet.
However, if returning to this section to enable shadowing, you should reset any
current user passwords with the <command>passwd</command> command or any
group passwords with the <command>gpasswd</command> command.</para>
