30 <identifier>authn_anon_module</identifier>
31 <compatibility>Available in Apache 2.1 and later</compatibility>
34 <p>This module provides authentication front-ends such as
35 <module>mod_auth_basic</module> 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 <module>mod_auth_basic</module>, this module is invoked
49 via the <directive module="mod_auth_basic">AuthBasicProvider</directive>
50 directive with the <code>anon</code> value.</p>
53 <section id="example"><title>Example</title>
54 <p>The example below is combined with "normal" htpasswd-file based
55 authentication and allows users in additionally as 'guests' with the
56 following properties:</p>
59 <li>It insists that the user enters a userID.
60 (<directive module="mod_authn_anon"
61 >Anonymous_NoUserID</directive>)</li>
63 <li>It insists that the user enters a password.
64 (<directive module="mod_authn_anon"
65 >Anonymous_MustGiveEmail</directive>)</li>
67 <li>The password entered must be a valid email address, <em>i.e.</em>
68 contain at least one '@' and a '.'.
69 (<directive module="mod_authn_anon"
70 >Anonymous_VerifyEmail</directive>)</li>
72 <li>The userID must be one of <code>anonymous guest www test
73 welcome</code> and comparison is <strong>not</strong> case
74 sensitive. (<directive module="mod_authn_anon"
75 >Anonymous</directive>)</li>
77 <li>And the Email addresses entered in the passwd field are
78 logged to the error log file.

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