Squid Logfiles <> NT User names

Hi I have Squid running, and was wondering if its possible to get the access.log files to rather than log the machine name, log the NT user name? I have Squid running on Linux at work, but am also testing it on NT at home... Any ideas Gary _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
