+    <title>DESCRIPTION</title>
+    <para>
+      <filename>shadow</filename> is a file which contains the password
+      information for the system's accounts and optional aging
+      information.
+    </para>
+
+    <para>
+      This file must not be readable by regular users if password security
+      is to be maintained.
+    </para>
+
+    <para>
+      Each line of this file contains 9 fields, separated by colons
+      (<quote>:</quote>), in the following order:
+    </para>
+
+    <variablelist>
+      <varlistentry>
+	<term><emphasis role="bold">login name</emphasis></term>
+	<listitem>
+	  <para>
+	    It must be a valid account name, which exist on the system.
+	  </para>
+	</listitem>
+      </varlistentry>
+      <varlistentry>
+	<term><emphasis role="bold">encrypted password</emphasis></term>
+	<listitem>
+	  <para>
+	    This field may be empty, in which case no passwords are
+	    required to authenticate as the specified login name.
+	    However, some applications which read the
+	    <filename>/etc/shadow</filename> file may decide not to permit
+	    any access at all if the password field is empty.
+	  </para>
+	  <para>
+	    A password field which starts with an exclamation mark means
+	    that the password is locked.  The remaining characters on the
+	    line represent the password field before the password was
+	    locked.
+	  </para>
+	  <para>
+	    Refer to <citerefentry><refentrytitle>crypt</refentrytitle>
+	    <manvolnum>3</manvolnum></citerefentry> for details on how
+	    this string is interpreted.
+	  </para>
+	  <para>
+	    If the password field contains some string that is not a valid
+	    result of <citerefentry><refentrytitle>crypt</refentrytitle>
+	    <manvolnum>3</manvolnum></citerefentry>, for instance ! or *,
+	    the user will not be able to use a unix password to log in
+	    (but the user may log in the system by other means).

+      </varlistentry>
+      <varlistentry>
+	<term>
+	  <emphasis role="bold">date of last password change</emphasis>
+	</term>
+	<listitem>
+	  <para>
+	    The date of the last password change, expressed as the number
+	    of days since Jan 1, 1970.
+	  </para>
+	  <para>
+	    The value 0 has a special meaning, which is that the user
+	    should change her password the next time she will log in the
+	    system.
+	  </para>
+	  <para>
+	    An empty field means that password aging features are
+	    disabled.
+	  </para>
+	</listitem>
+      </varlistentry>
+      <varlistentry>
+	<term><emphasis role="bold">minimum password age</emphasis></term>
+	<listitem>
+	  <para>
+	    The minimum password age is the number of days the user will
+	    have to wait before she will be allowed to change her password
+	    again.
+	  </para>
+	  <para>
+	    An empty field and value 0 mean that there are no minimum
+	    password age.
+	  </para>
+	</listitem>
+      </varlistentry>
+      <varlistentry>
+	<term><emphasis role="bold">maximum password age</emphasis></term>
+	<listitem>
+	  <para>
+	    The maximum password age is the number of days after which the
+	    user will have to change her password.
+	  </para>
+	  <para>
+	    After this number of days is elapsed, the password may still
+	    be valid.  The user should be asked to change her password the
+	    next time she will log in.
+	  </para>
+	  <para>
+	    An empty field means that there are no maximum password age,
+	    no password warning period, and no password inactivity period
+	    (see below).
+	  </para>
+	  <para>
+	    If the maximum password age is lower than the minimum password
+	    age, the user cannot change her password.
+	  </para>
+	</listitem>
+      </varlistentry>
+      <varlistentry>
+	<term>
+	  <emphasis role="bold">password warning period</emphasis>
+	</term>
+	<listitem>
+	  <para>
+	    The number of days before a password is going to expire (see
+	    the maximum password age above) during which the user should
+	    be warned.
+	  </para>
+	  <para>
+	    An empty field and value 0 mean that there are no password
+	    warning period.
+	  </para>
+	</listitem>
+      </varlistentry>
+      <varlistentry>
+	<term>
+	  <emphasis role="bold">password inactivity period</emphasis>
+	</term>
+	<listitem>
+	  <para>
+	    The number of days after a password has expired (see the
+	    maximum password age above) during which the password should
+	    still be accepted (and the user should update her password
+	    during the next login).
+	  </para>
+	  <para>
+	    After expiration of the password and this expiration period is
+	    elapsed, no login is possible using the current user's
+	    password.  The user should contact her administrator.
+	  </para>
+	  <para>
+	    An empty field means that there are no enforcement of an
+	    inactivity period.
+	  </para>
+	</listitem>
+      </varlistentry>
+      <varlistentry>
+	<term>
+	  <emphasis role="bold">account expiration date</emphasis>
+	</term>
+	<listitem>
+	  <para>
+	    The date of expiration of the account, expressed as the number
+	    of days since Jan 1, 1970.
+	  </para>
+	  <para>
+	    Note that an account expiration differs from a password
+	    expiration.  In case of an account expiration, the user shall
+	    not be allowed to login.  In case of a password expiration,
+	    the user is not allowed to login using her password.
+	  </para>
+	  <para>
+	    An empty field means that the account will never expire.
+	  </para>
+	  <para>
+	    The value 0 should not be used as it is interpreted as either
+	    an account with no expiration, or as an expiration on Jan 1,
+	    1970.
