Summary
This module 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.
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.

(
Anonymous_NoUserID) - It insists that the user enters a password.
(
Anonymous_MustGiveEmail) - The password entered must be a valid email address, ie.
contain at least one '@' and a '.'.
(
Anonymous_VerifyEmail) - The userID must be one of
anonymous guest www test welcomeand comparison is not case sensitive. (Anonymous) - And the Email addresses entered in the passwd field are
logged to the error log file.

AuthType basic
# An
AuthUserFile/AuthDBUserFile/AuthDBMUserFile

Anonymous Директива
| Описание: | Specifies userIDs that are allowed access without password verification |
|---|---|
| Синтаксис: | Anonymous user [user] ... |
| Контекст: | directory, .htaccess |
| Перекрывает: | AuthConfig |
| Статус: | Extension |
| Модуль: | mod_auth_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.
I strongly suggest that the magic username
'anonymous' is always one of the allowed
userIDs.
Пример:
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".
Anonymous_Authoritative Директива
| Описание: | Configures if authorization will fall-through to other methods |
|---|---|
| Синтаксис: | Anonymous_Authoritative On|Off |
| По умолчанию: | Anonymous_Authoritative Off |
| Контекст: | directory, .htaccess |
| Перекрывает: | AuthConfig |
| Статус: | Extension |
| Модуль: | mod_auth_anon |
When set On, there is no fall-through to other
authentication methods. So if a userID does not match the values
specified in the Anonymous
directive, access is denied.
Be sure you know what you are doing when you decide to switch it on. And remember that the order in which the Authentication modules are queried is defined in the modules.c files at compile time.
Anonymous_LogEmail Директива
| Описание: | Sets whether the password entered will be logged in the error log |
|---|---|
| Синтаксис: | Anonymous_LogEmail On|Off |
| По умолчанию: | Anonymous_LogEmail On |
| Контекст: | directory, .htaccess |
| Перекрывает: | AuthConfig |
| Статус: | Extension |
| Модуль: | mod_auth_anon |
When set On, the default, the 'password' entered
(which hopefully contains a sensible email address) is logged in
the error log.
Anonymous_MustGiveEmail Директива
| Описание: | Specifies whether blank passwords are allowed |
|---|---|
| Синтаксис: | Anonymous_MustGiveEmail On|Off |
| По умолчанию: | Anonymous_MustGiveEmail On |
| Контекст: | directory, .htaccess |
| Перекрывает: | AuthConfig |
| Статус: | Extension |
| Модуль: | mod_auth_anon |
Specifies whether the user must specify an email address as the password. This prohibits blank passwords.
Anonymous_NoUserID Директива
| Описание: | Sets whether the userID field may be empty |
|---|---|
| Синтаксис: | Anonymous_NoUserID On|Off |
| По умолчанию: | Anonymous_NoUserID Off |
| Контекст: | directory, .htaccess |
| Перекрывает: | AuthConfig |
| Статус: | Extension |
| Модуль: | mod_auth_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 Директива
| Описание: | Sets whether to check the password field for a correctly formatted email address |
|---|---|
| Синтаксис: | Anonymous_VerifyEmail On|Off |
| По умолчанию: | Anonymous_VerifyEmail Off |
| Контекст: | directory, .htaccess |
| Перекрывает: | AuthConfig |
| Статус: | Extension |
| Модуль: | mod_auth_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).
