|
|
|
|
This module is contained in the <CODE>mod_auth_anon.c</CODE> file and
|
|
is not compiled in by default. It is only available in Apache 1.1 and
|
|
later. It allows "anonymous" user access to authenticated areas.
|
|
|
|
<H2>Summary</H2>
|
|
|
|
It does access control in a manner similar to anonymous-ftp sites; i.e.
|
|
have a 'magic' user id 'anonymous' and the email address as a password.
|
|
These email addresses can be logged.
|
|
<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.
|
|

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>
|
|
Please note that the comparison is <STRONG>case-IN-sensitive</STRONG>.
|
|
<BR>
|
|
I strongly suggest that the magic username '<CODE>anonymous</CODE>'
|
|
is always one of the allowed userIDs.
|
|
<P>
|
|
Example:<BR>
|
|
<CODE>
|
|
Anonymous anonymous "Not Registered" 'I don\'t know'
|
|
</CODE><P>
|
|
This would allow the user to enter without password verification
|
|
by using the userId's 'anonymous', 'AnonyMous','Not Registered' and
|
|
'I Don't Know'.

When set 'on', there is no
|
|
fall-through to other authorization methods. So if a
|
|
userID does not match the values specified in the
|
|
<CODE>Anonymous</CODE> directive, access is denied.
|
|
<P>
|
|
Be sure you know what you are doing when you decide to switch
|
|
it on. And remember that it is the linking order of the modules
|
|
(in the Configuration / Make file) which details the order
|
|
in which the Authorization modules are queried.

When set 'on', 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.
