Squid: The Definitive Guide

Name

auth_param

Synopsis

The auth_param directive controls almost every aspect of Squid’s external user authentication interface. Squid currently supports three authentication schemes: Basic, Digest, and NTLM. Basic authentication support is compiled by default. For the others, you must use the —enable-auth option with ./configure.

Since the auth_param directive is very complex, I’m presenting it here as a separate directive for each combination of parameters.
