Apache HTTP Server Version 2.2
Apache Module mod_authn_anon
|Description:||Allows "anonymous" user access to authenticated areas|
|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.
The example below is combined with "normal" htpasswd-file based authentication and allows users in additionally as 'guests' with the following properties:
- It insists that the user enters a userID.
- It insists that the user enters a password.
- The password entered must be a valid email address, i.e.
contain at least one '@' and a '.'.
- The userID must be one of
anonymous guest www test welcomeand comparison is not case sensitive. (
- And the Email addresses entered in the passwd field are
logged to the error log file.

|Description:||Specifies userIDs that are allowed access without password verification|
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
It's strongly recommended that the magic username '
anonymous' is always one of the allowed
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
|Description:||Sets whether the password entered will be logged in the error log|
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|
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|
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|
On the 'password' entered is checked for
at least one '@' and a '.' to encourage users to enter valid email
addresses (see the above
