Thanks to those who replied. Here's a recount of my experience.

On RHEL ESv3, the latest squid update (squid-2.5.STABLE3-6.3E.i386.rpm)
breaks NTLM for us.

This was evidenced by the username field in the access logs coming up as
either just the domain (ie domain not domain/user) or domain3/user. Some
authentication based access was also broken such that access was denied.

I had a look in bot /var/cache/up2date (this one doesn't exist) and
/var/spool/up2date but I suspect the latter was cleared after a reboot.

Fortunately I have set up2date to store and keep files in the same shared
directory far all RH machines. I still had the previous update here.

To "update" an rpm with an earlier version use:
# rpm -Uvh --oldpackage squid-2.5.STABLE3-5.3E.i386.rpm
Preparing...           ########################################### [100%]
   1:squid             ########################################### [100%]
#

Authentication has returned to normal.
