Apache HTTP Server Version 2.2
| Description: | Allows "anonymous" user access to authenticated areas |
|---|---|
| Status: | Extension |
| Module Identifier: | authn_anon_module |
| Source File: | mod_authn_anon.c |
| Compatibility: | Available in Apache 2.1 and later |
This module provides authentication front-ends such as
mod_auth_basic to authenticate users 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.
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.
When using mod_auth_basic, this module is invoked
via the AuthBasicProvider
directive with the anon value.
The example below is combined with "normal" htpasswd-file based authentication and allows users in additionally as 'guests' with the following properties:
Anonymous_NoUserID)Anonymous_MustGiveEmail)Anonymous_VerifyEmail)anonymous guest www test
welcome and comparison is not case
sensitive. (Anonymous)Anonymous_LogEmail)
<Directory /foo>
AuthName "Use 'anonymous' & Email address for guest entry"
AuthType Basic
AuthBasicProvider file anon
AuthUserFile /path/to/your/.htpasswd
Anonymous_NoUserID off
Anonymous_MustGiveEmail on
Anonymous_VerifyEmail on
Anonymous_LogEmail on
Anonymous anonymous guest www test welcome
Order Deny,Allow
Allow from all
Require valid-user
</Directory>
| Description: | Specifies userIDs that are allowed access without password verification |
|---|---|
| Syntax: | Anonymous user [user] ... |
| Context: | directory, .htaccess |
| Override: | AuthConfig |
| Status: | Extension |
| Module: | mod_authn_anon |
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.
Please note that the comparison is
case-IN-sensitive.
It's strongly recommended that the magic username
'anonymous' is always one of the allowed
userIDs.
Anonymous anonymous "Not Registered" "I don't know"
This would allow the user to enter without password verification by using the userIDs "anonymous", "AnonyMous", "Not Registered" and "I Don't Know".
As of Apache 2.1 it is possible to specify the userID as
"*". That allows any supplied userID to be
accepted.
| Description: | Sets whether the password entered will be logged in the error log |
|---|---|
| Syntax: | Anonymous_LogEmail On|Off |
| Default: | Anonymous_LogEmail On |
| Context: | directory, .htaccess |
| Override: | AuthConfig |
| Status: | Extension |
| Module: | mod_authn_anon |
When set On, the default, the 'password' entered
(which hopefully contains a sensible email address) is logged in
the error log.
| Description: | Specifies whether blank passwords are allowed |
|---|---|
| Syntax: | Anonymous_MustGiveEmail On|Off |
| Default: | Anonymous_MustGiveEmail On |
| Context: | directory, .htaccess |
| Override: | AuthConfig |
| Status: | Extension |
| Module: | mod_authn_anon |
Specifies whether the user must specify an email address as the password. This prohibits blank passwords.
| Description: | Sets whether the userID field may be empty |
|---|---|
| Syntax: | Anonymous_NoUserID On|Off |
| Default: | Anonymous_NoUserID Off |
| Context: | directory, .htaccess |
| Override: | AuthConfig |
| Status: | Extension |
| Module: | mod_authn_anon |
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.
| Description: | Sets whether to check the password field for a correctly formatted email address |
|---|---|
| Syntax: | Anonymous_VerifyEmail On|Off |
| Default: | Anonymous_VerifyEmail Off |
| Context: | directory, .htaccess |
| Override: | AuthConfig |
| Status: | Extension |
| Module: | mod_authn_anon |
When set On the 'password' entered is checked for
at least one '@' and a '.' to encourage users to enter valid email
addresses (see the above Anonymous_LogEmail).
