Squid authentication

["plutoplanet" <plutoplanet@free.net.nz>]

Hi,
   I'm trying configure squid to make users authenticate if they try
getting to any other sites that I have not specified as ok for all
users.  But when it goes to authenticate it regects the user name and
password and I get the folling error come up in the /var/log/syslog
file
proxy squid[1284]: WARNING: authenticator #1 (FD 1) exited

The relevent lines in my squid.conf are as follows

authenticate_program /usr/lib/squid/ncsa_auth /etc/shadow
acl trusted proxy_auth REQUIRED
http_access allow proxy_auth

can someone help please.

Thanks
Jamil
