Apache::AuthenPasswd - mod_perl /etc/passwd Authentication module
# This is the standard authentication stuff
AuthName "Foo Bar Authentication"
# Standard require stuff, /etc/passwd users or /etc/group groups, and
# "valid-user" all work OK
require user username1 username2 ...
require group groupname1 groupname2 ... # [Need Apache::AuthzPasswd]
# The following is actually only needed when authorizing
# against /etc/group. This is a separate module.
These directives can also be used in the <Location> directive or in
an .htaccess file.
= head1 DESCRIPTION
**************** NOTICE *********************
Please, please, realize that this module will
only work with passwords that are stored in
/etc/passwd. Most systems use shadow
passwords now, and the call that this module
uses to access the password ONLY checks for
the password in the /etc/passwd file. Also,
the call that is needed to access passwords
in /etc/shadow cannot be called by anyone
other than root, so, (unless you are crazy
enough to run apache as root), you will not
be able to access /etc/shadow.

This perl module is designed to work with mod_perl. It is a direct adaptation (i.e. I modified the code) of Michael Parker's (firstname.lastname@example.org) Apache::AuthenSmb module.
The module uses getpwnam to retrieve the passwd entry from the /etc/passwd file, using the supplied username as the search key. It then uses crypt() to verify that the supplied password matches the retrieved hashed password.
= head2 Apache::AuthenPasswd vs. Apache::AuthzPasswd
I've taken "authentication" to be meaningful only in terms of a user and password combination, not group membership. This means that you can use Apache::AuthenPasswd with the require user and require valid-user directives. In the /etc/passwd and /etc/group context I consider require group to be an "authorization" concern. I.e., group authorization consists of establishing whether the already authenticated user is a member of one of the indicated groups in the require group directive. This process may be handled by Apache::AuthzPasswd. Admittedly, AuthzPasswd is a misnomer, but I wanted to keep AuthenPasswd and AuthzPasswd related, if only by name.
I welcome any feedback on this module, esp. code improvements, given that it was written hastily, to say the least.
