<h3>Summary</h3>
<p>This module provides authentication front-ends such as
<code class="module"><a href="/mod/mod_auth_basic.html">mod_auth_basic</a></code> to authenticate users similar
to anonymous-ftp sites, <em>i.e.</em> have a 'magic' user id
'anonymous' and the email address as a password. These email
addresses can be logged.</p>
<p>Combined with other (database) access control methods, this
allows for effective user tracking and customization according
to a user profile while still keeping the site open for
'unregistered' users. One advantage of using Auth-based user
tracking is that, unlike magic-cookies and funny URL
pre/postfixes, it is completely browser independent and it
allows users to share URLs.</p>
<p>When using <code class="module"><a href="/mod/mod_auth_basic.html">mod_auth_basic</a></code>, this module is invoked
via the <code class="directive"><a href="/mod/mod_auth_basic.html#authbasicprovider">AuthBasicProvider</a></code>
directive with the <code>anon</code> value.</p>

<p>The example below is combined with "normal" htpasswd-file based
authentication and allows users in additionally as 'guests' with the
following properties:</p>

<li>It insists that the user enters a userID.
(<code class="directive"><a href="#anonymous_nouserid">Anonymous_NoUserID</a></code>)</li>
<li>It insists that the user enters a password.
(<code class="directive"><a href="#anonymous_mustgiveemail">Anonymous_MustGiveEmail</a></code>)</li>
<li>The password entered must be a valid email address, <em>i.e.</em>
contain at least one '@' and a '.'.
(<code class="directive"><a href="#anonymous_verifyemail">Anonymous_VerifyEmail</a></code>)</li>
<li>The userID must be one of <code>anonymous guest www test
welcome</code> and comparison is <strong>not</strong> case
sensitive. (<code class="directive"><a href="#anonymous">Anonymous</a></code>)</li>
<li>And the Email addresses entered in the passwd field are
logged to the error log file.

<p>A list of one or more 'magic' userIDs which are allowed
access without password verification. The userIDs are space
separated. It is possible to use the ' and " quotes to allow a
space in a userID as well as the \ escape character.</p>
<p>Please note that the comparison is
<strong>case-IN-sensitive</strong>.<br />
It's strongly recommended that the magic username
'<code>anonymous</code>' is always one of the allowed
userIDs.</p>
<div class="example"><h3>Example:</h3><p><code>
Anonymous anonymous "Not Registered" "I don't know"
</code></p></div>
<p>This would allow the user to enter without password
verification by using the userIDs "anonymous",
"AnonyMous", "Not Registered" and "I Don't Know".</p>
<p>As of Apache 2.1 it is possible to specify the userID as
"<code>*</code>". That allows <em>any</em> supplied userID to be
accepted.</p>

<p>When set <code>On</code>, users can leave the userID (and
perhaps the password field) empty. This can be very convenient for
MS-Explorer users who can just hit return or click directly on the
OK button; which seems a natural reaction.</p>

<p>When set <code>On</code> the 'password' entered is checked for
at least one '@' and a '.' to encourage users to enter valid email
addresses (see the above <code class="directive"><a href="#anonymous_logemail">Anonymous_LogEmail</a></code>).</p>
