[squid-users] upgrade to squid 3.0 breaking existing authentication module

Dear all,

I use squid on my personal computer to provide HTTP proxy service to my
friends at college. I'm not a sysadmin --- just using squid occasionally
when necessary. I use a basic authenticator module written in Perl by
Thomas Börnert "squidauth.pl" <http://www.tbits.org/html/squidauth.html>.

The problem was like this. I recently upgraded my squid version from 2.6
to 3.0 after an OS upgrade. Back in the 2.6 days the module worked fine.
After I ported the authentication part of my squid.conf to the 3.0
version, it stopped working. After the squid service was started, the
authenticator processes got terminated unexpectedly. I looked at my logs
and found the suspicious lines (from /var/log/squid/cache.log):

This strange behavior was not encountered with the 2.6 version. I have
no idea about the ipcCreate failures. I have offline-tested the
authenticator which turned out to be working properly.

I'd be glad to hear your suggestions.

Thanks in advance.
