Issues with SQUID and Windows 7 ultimate

These days i found a little strange issue on my network related to SQUID users' authenticaion through domain membership.
It seems that the vista line of OSs (Vista-Win7-Win2008 srv) brought some changes to NTLM authentication scheme. The result is that browsers on systems running windows 7 ultimate could authenticate users through Active directory. After some research, i found that you have to change some options concerning NTLM in local security settings, to allow for less strict security requirements.
  1. Open local security console -> computer configuration->windows setting->local policies->security option->Network security: LAN Manager authentication -> Send both LM & NTLM.
