ncsa_auth(8) System Manager's Manual ncsa_auth(8)NAME
ncsa_auth - NCSA httpd-style password file authentication helper for Squid
SYNOPSIS
ncsa_auth passwdfile
DESCRIPTION
ncsa_auth allows Squid to read and authenticate user and password information from an NCSA/Apache httpd-style password file when using
basic HTTP authentication.
The only parameter is the password file. It must have permissions to be read by the user that Squid is running as (cache_effective_user in
squid.conf).
This password file can be manipulated using htpasswd.
* MD5 - with optional salt and magic strings * DES - for passwords 8 characters or less in length
OPTIONS
Only specify the password file name.
EXAMPLE
ncsa_auth /etc/squid/squid.pass
SECURITY
ncsa_auth must have access to the password file to be executed.
KNOWN ISSUES
DES functionality (used by htpasswd by default) silently truncates passwords to 8 characters. Allowing login with password values shorter
than the one desired. This authenticator will reject login with long passwords when using DES.

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 authentica-
tion.
-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 speci-
fies 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 can-
not 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.
