        The above two commands can be omitted if the following directive is
        placed in the configuration file:

<screen><literal>RequireValidShell off</literal></screen>

      <para>
        By default, proftpd will require that users logging in have valid
        shells. The RequireValidShell directive turns off this requirement.
        This is only recommended if you are setting up your FTP server
        exclusively for anonymous downloads.
