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 "/var/www/html/private"> 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 Require valid-user </Directory>

Syntax: | Anonymous user [user] ... |
Context: | directory, .htaccess |

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.
