<p>This module provides authentication front-ends such as
37
<code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> to authenticate users similar
38
to anonymous-ftp sites, <em>i.e.</em> have a 'magic' user id
39
'anonymous' and the email address as a password. These email
40
addresses can be logged.</p>
42
<p>Combined with other (database) access control methods, this
43
allows for effective user tracking and customization according
44
to a user profile while still keeping the site open for
45
'unregistered' users. One advantage of using Auth-based user
46
tracking is that, unlike magic-cookies and funny URL
47
pre/postfixes, it is completely browser independent and it
48
allows users to share URLs.</p>
50
<p>When using <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code>, this module is invoked
51
via the <code class="directive"><a href="../mod/mod_auth_basic.html#authbasicprovider">AuthBasicProvider</a></code>
52
directive with the <code>anon</code> value.</p>

<p>A list of one or more 'magic' userIDs which are allowed
127
access without password verification. The userIDs are space
128
separated. It is possible to use the ' and " quotes to allow a
129
space in a userID as well as the \ escape character.</p>
131
<p>Please note that the comparison is
132
<strong>case-IN-sensitive</strong>.<br />
133
It's strongly recommended that the magic username
134
'<code>anonymous</code>' is always one of the allowed

verification by using the userIDs "anonymous",
143
"AnonyMous", "Not Registered" and "I Don't Know".</p>
145
<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

<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
