34 <p>This module provides authentication front-ends such as
35 <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> to authenticate users similar
36 to anonymous-ftp sites, <em>i.e.</em> have a 'magic' user id
37 'anonymous' and the email address as a password. These email
38 addresses can be logged.</p>
40 <p>Combined with other (database) access control methods, this
41 allows for effective user tracking and customization according
42 to a user profile while still keeping the site open for
43 'unregistered' users. One advantage of using Auth-based user
44 tracking is that, unlike magic-cookies and funny URL
45 pre/postfixes, it is completely browser independent and it
46 allows users to share URLs.</p>
48 <p>When using <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code>, this module is invoked
49 via the <code class="directive"><a href="../mod/mod_auth_basic.html#authbasicprovider">AuthBasicProvider</a></code>
50 directive with the <code>anon</code> value.</p>
