[6a9875d]5<para>This package contains utilities to modify users' passwords, add
[2b114b25]6or delete users and groups, and the like. We're not going to explain what
[360e2c4]7'password shadowing' means. A full explanation can be found in the
8<filename>doc/HOWTO</filename>
9file within the unpacked Shadow source tree. There's one
10thing to keep in mind if you decide to use Shadow support: programs that
[2b114b25]11need to verify passwords (for example xdm, ftp daemons, pop3 daemons) need
12to be 'shadow-compliant', that is they need to be able to work with
[e4b9338]13shadowed passwords.</para>
[6370fa6]14
[91b45ad]15<para>To enable shadowed passwords, run the following command:</para>
[6370fa6]16
[21ba4e3]17<screen><userinput>/usr/sbin/pwconv</userinput></screen>
[6370fa6]18
[de488c7]19<para>And to enable shadowed group passwords, run the following
20command:</para>
21
[21ba4e3]22<screen><userinput>/usr/sbin/grpconv</userinput></screen>
[de488c7]23
[d5d57b1]24<para>Under normal circumstances, you won't have created any passwords yet.
25However, if returning to this section to enable shadowing, you should reset any
26current user passwords with the <userinput>passwd</userinput> command or any
27group passwords with the <userinput>gpasswd</userinput> command.</para>
