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 connection 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.
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.
