NAME

Apache2::AuthPAM - Authenticate apache request using PAM services

SYNOPSIS

# /etc/httpd.conf
<Directory /var/www/https/secured-area/>
   AuthType Basic
   AuthName "your server account"
   PerlAuthenHandler Apache2::AuthPAM
   PerlSetVar PAMservice check_user
   require valid-user
</Directory>

The PAMservice value above corresponds to the name of a PAM config file. You can use an existing filename, of create a new one with a custom configuration. For example:

# /etc/pam.d/check_user
#%PAM-1.0
auth        required    /lib/security/pam_pwdb.so nodelay
account     required    /lib/security/pam_pwdb.so

DESCRIPTION

This perl module is designed to work with mod_perl2 and the Authen::PAM module.

You can select the PAM service setting the perl var PAMservice

PerlSetVar PAMservice the-pam-service-you-want

You can select different PAM services for different directories or locations in your web server filesystem space.

Apache2::AuthPAM works as follows:

calls pam_start with the selected service.
calls pam_authenticate with the browser/apache supplied username and password.
calls pam_acct_mgmt.
calls pam_end.

If any of the PAM functions fail, Apache2::AuthPAM logs an info level message and returns AUTH_REQUIRED. If all PAM functions are succesfull, Apache2::AuthPAM logs an info level message and returns OK.

Remember that if you don't use https (SSL) then your username and password is transmitted on the network in plain text with each request. So if you are going to use your system password database, you MUST also use mod_ssl or you accounts will be easily compromised.

BUGS

Apache2::AuthPAM is running as the same user mod_perl is running (on RedHat Linux it is apache). It is running without privileges.
