basic_getpwnam_auth(8) System Manager's Manual basic_getpwnam_auth(8)
NAME
basic_getpwnam_auth - Local Users auth helper for Squid
SYNOPSIS
basic_getpwnam_auth
DESCRIPTION
basic_getpwnam_auth allows Squid to authenticate any local user ac-
counts to validate the user name and password of Basic HTTP authentica-
tion.
It uses getpwnam() and getspnam() routines for authentication.
This has the following advantages over the NCSA module:
- Allows authentication of all known local users
- Allows authentication through nsswitch.conf
- Can handle NIS(+) requests
- Can handle LDAP requests
- Can handle PAM requests
CONFIGURATION
auth_param basic program /path/to/basic_getpwnam_auth
auth_param basic children concurrency=1
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_getpwnam_auth
chmod u+s basic_getpwnam_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.
