Samba 4 vs Squid 3.2 - NTLM Authentication

[Aecio Alves]

Good afternoon.

I'm trying to make the integrated authentication between Samba and Squid 
3.2.0.1 4. My scenario is as follows:

- A server running Samba 4 as a Domain Controller and Squid to filter 
the users' navigation.

The domain is properly configured and squid too. No authentication squid 
works perfectly, but when I enable authentication it stops working.

Sometimes it starts loading the page, but not complete and stops working.

Could you help me?

Thank you
