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.
