[squid-users] writing my own authenticator

so ip_user wont actually do what i want ( the book isnt clear actually
what it is there for) - thanks Henrik

what i want is to get the currently logged-in user and pass it to squid
which will then authenticate against that with no further dialog boxes etc
 . i can then add eg time-based ACLs

So i thought id try my own. eventually i suspect i'll use gewtpwuid() and
look up in /etc/passwd.

#!/usr/bin/perl -wl
$|=1;
 my @names=("andrew","anne","nick","emma");
my $username = `whoami` or die "Couldn't execute command: $!";
   chomp($username);
open (F, '>/tmp/data.txt');
print F "$username\n";
close (F);
my $i=0;
while ($i<$#names)
{
if ($names[$i] eq $username){print "OK user=$username";exit;}
$i++;
}
print "ERR";

and this returns the current user and writes it to the file.

my squid.conf

hepworth andrew # cat /etc/squid/squid.conf |grep ^acl
acl all src 0.0.0.0/0.0.0.0

do i need an auth_param directive as well ? if so what ?

so when i request a web page it asks me for a username and password and
myaclhelper doesnt write the text file. Should it be doing the
