basic_sasl_auth — Basic Authentication using SASL (specifically the cyrus-sasl authentication method)

Version 1.0

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/setgid 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 configuration file basic_sasl_auth.pam is also included.
