NAME

pam_auth - Squid PAM authentication helper

SYNOPSIS

squid_pam_auth [-n "service name"] [-t TTL] [-o] [-1]

DESCRIPTION

This helper allows Squid to connect to a mostly any available PAM database to validate the user name and password of Basic HTTP authentication.
-s service-name

Specifies the PAM service name Squid uses, defaults to "squid"

-t TTL

Enables persistent PAM connections where the connection to the PAM database is kept open and reused for new logins. The TTL specifies how long the connetion will be kept open (in seconds). Default is to not keep PAM connections open. Please note that the use of persistent PAM connections is slightly outside the PAM specification and may not work with all PAM configurations.

-o

Do not perform the PAM account management group (account expiration etc)

CONFIGURATION

The program needs a PAM service to be configured in /etc/pam.conf or /etc/pam.d/<servicename>

The default service name is "squid", and the program makes use of the ’auth’ and ’account’ management groups to verify the password and the accounts validity.

For details on how to configure PAM services, see the PAM documentation for your system. This manual does not cover PAM configuration details. The existing PAM service definitions for other applications on your system is also a good source for examples on how to configure a PAM service.

NOTES

When used for authenticating to local UNIX shadow password databases the program must be running as root or else it won’t have sufficient permissions to access the user password database. Such use of this program is not recommended, but if you absolutely need to then make the program setuid root

chown root pam_auth
chmod u+s pam_auth

Please note that in such configurations it is also strongly recommended that the program is moved into a directory where normal users cannot access it, as this mode of operation will allow any local user to brute-force other users passwords. Also note the program has not been fully audited and the author cannot be held responsible for any security issues due to such installations.
