概述

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.

Example

The example below is combined with "normal" htpasswd-file based authentication and allows users in additionally as 'guests' with the following properties:

示例

<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>

Anonymous 指令

说明Specifies userIDs that are allowed access without password verification
语法Anonymous user [user] ...
作用域directory, .htaccess
覆盖项AuthConfig
状态扩展(E)
模块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.

示例:

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.

Anonymous_MustGiveEmail 指令

说明Specifies whether blank passwords are allowed
语法Anonymous_MustGiveEmail On|Off
默认值Anonymous_MustGiveEmail On
作用域directory, .htaccess
覆盖项AuthConfig
状态扩展(E)

Anonymous_NoUserID 指令

说明Sets whether the userID field may be empty
语法Anonymous_NoUserID On|Off
默认值Anonymous_NoUserID Off
作用域directory, .htaccess
覆盖项AuthConfig
状态扩展(E)
模块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.

Anonymous_VerifyEmail 指令

说明Sets whether to check the password field for a correctly formatted email address
语法Anonymous_VerifyEmail On|Off
默认值Anonymous_VerifyEmail Off
作用域directory, .htaccess
覆盖项AuthConfig
状态扩展(E)
模块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).
