basic_ncsa_auth(8) System Manager's Manual basic_ncsa_auth(8) 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 in- formation 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 pass- words to 8 characters. Allowing login with password values shorter than the one desired. This authenticator will reject login with long passwords when using DES.
