basic_pam_auth - PAM Basic authentication helper for Squid
TTL ] [-o] [-1]
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
- -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.
- Do not perform the PAM account management group (account
The program needs a PAM service to be configured in /etc/pam.conf
The default service name is squid
, and the program makes use of the
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.
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 basic_pam_auth
chmod u+s basic_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.
