<h2 align="center"><em>WN</em> Password Protected Directory Example</h2>
<hr size="4">
<p>
This file is accessible only to user <code>santa</code> with password
<code>red-nosed</code> or user <code>rudolph</code> with password
<code>NorthPole</code>.
</p>
<p>
Here is what the <code>index</code> file for this directory looks like:
</p>
<blockquote>
<pre>
<!-- #include -->
</pre>
</blockquote>
<p>
The realm lets the client know that the same user/password pair is valid
for any other directory with the same realm. The "<code><a
href="../appendixB.html#ddir.authorization-module">Authorization-module=</a></code>"
line specifies that we are using the module <code><a
href="../module.html#authorization">wnauth</a></code> which comes as part
of the <em>WN</em> package. The <code>-P</code> option indicates that
the next argument is the name of the password file we are using. A UNIX
NDBM database can also be used for a password file. You can also control
access by groups.
</p>
<p>
Finally all documents in this directory, being password protected, should
not be cached so we give the directory the "<code><a
href="../appendixB.html#ddir.default-attributes">Default-Attributes=</a><a
href="../appendixB.html#fdir.attributes.non-cachable">non-cachable</a></code>".
This is done for security reasons on the client as not all clients
adequately protect the documents they cache.
</p>
<p>
You can read the section "<a href="../access.html#authenticate">Limiting
Access by Password Authentication</a>" from the "<a
href="../manual.html">User's Guide for the <em>WN</em> Server</a>" for
more information about password protecting documents under <em>WN</em>.
