NAME basic_ncsa_auth - NCSA httpd-style password file authentication helper for Squid
SYNOPSIS basic_ncsa_auth passwd file
DESCRIPTION basic_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. This password file can be manipulated using htpasswd. This authenticator accepts: * Blowfish - for passwords 72 characters or less in length * SHA256 - with salting and magic strings * SHA512 - with salting and magic strings * MD5 - with optional salt and magic strings * DES - for passwords 8 characters or less in length NOTE: Blowfish and SHA algorithms require system-specific support.
OPTIONS The only parameter is the password file. It must have permissions to be read by the user that Squid is running as.
CONFIGURATION basic_ncsa_auth /etc/squid/squid.pass basic_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 charac‐ ters. Allowing login with password values shorter than the one desired. This authentica‐ tor will reject login with long passwords when using DES.
