basic_pam_auth(8)basic_pam_auth(8)NAMEbasic_pam_auth - Squid PAM Basic authentication helper
SYNOPSISbasic_pam_auth [-n service name TTL ] [-o] [-1]
DESCRIPTIONbasic_pam_auth allows Squid to connect to a mostly any available PAM
database to validate the user name and password of Basic HTTP authenti‐
cation.
OPTIONS-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/squid
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 pro‐
gram 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 secu‐
rity issues due to such installations.
