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. AUTHOR

basic_sasl_auth(8) System Manager's Manual basic_sasl_auth(8) NAME
basic_sasl_auth - Basic Authentication using SASL (specifically the cyrus-sasl authentication method) Version 1.0 SYNOPSIS
basic_sasl_auth DESCRIPTION
basic_sasl_auth is an installed binary helper for Squid. SASL is configurable (somewhat like PAM). Each service authenticating against SASL identifies itself with an application name. Each application can be configured independently by the SASL administrator. CONFIGURATION
To configure the authentication method used the file basic_sasl_auth.conf can be placed in the appropriate location, usually /usr/lib/sasl. The authentication database is defined by the pwcheck_method parameter. Only the PLAIN authentication mechanism is used. Examples: pwcheck_method:sasldb use sasldb - the default if no conf file is installed. pwcheck_method:pam - use PAM authentication database pwcheck_method:passwd - use traditional /etc/passwd pwcheck_method:shadow - use slightly less traditional /etc/shadow Others methods may be supported by your cyrus-sasl implementation - consult your cyrus-sasl documentation for information. Typically the authentication database ( /etc/sasldb , /etc/shadow , PAM ) can not be accessed by a normal user. You should use setuid/set- gid and an appropriate user/group on the executable to allow the authenticator to access the appropriate password database. If the access to the database is not permitted then the authenticator will typically fail with "-1, generic error". chown root.mail basic_sasl_auth chmod ug+s basic_sasl_auth If the application name basic_sasl_auth will also be used for the PAM service name if pwcheck_method:pam is chosen. And example PAM config- uration file basic_sasl_auth.pam is also included. AUTHOR
