+    <para>
+      The <command>chpasswd</command> command reads a list of user name and
+      password pairs from standard input and uses this information to update
+      a group of existing users. Each line is of the format:

+      <emphasis remap='I'>user_name</emphasis>:<emphasis
+      remap='I'>password</emphasis>
+    </para>
+    <para>
+      By default the passwords must be supplied in clear-text, and are
+      encrypted by <command>chpasswd</command>.
+      Also the password age will be updated, if present.
+    </para>
+    <para condition="no_pam">
+      The default encryption algorithm can be defined for the system with
