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
       characters.   Allowing  login  with  password  values  shorter than the one desired.  This
       authenticator will reject login with long passwords when using DES.
