<tag><bf>Recognized arguments:</bf></tag>
<tag><bf>Description:</bf></tag>
Provides standard Unix <em/nologin/ authentication. If the file
<tt>/etc/nologin</tt> exists, only root is allowed to log in; other
users are turned away with an error message. All users (root or
otherwise) are shown the contents of <tt>/etc/nologin</tt>.
<p>
If the file <tt>/etc/nologin</tt> does not exist, this module succeeds
silently.
<tag><bf>Examples/suggested usage:</bf></tag>
In order to make this module effective, all login methods should
be secured by it. It should be used as a <tt>required</tt>
method listed before any <tt>sufficient</tt> methods in order to
get standard Unix nologin semantics.
