Hello Sorry my English is not the same as good. I have installed in my company with Squid 3.1.4 (Winbind, Samba, Kerberos), but I have noticed the following message in the file caches.log * got NTLMSSP command 3, expected 1* I searched the community and informed them that the problem is the type of authentication that clients are sending. But I found the solution. I really need your help. -- Atenciosamente, João Paulo Ferreira Computer Science Student + 55 (71) 9297 - 1260 jferreira.ba@xxxxxxxxx "Nunca diga para Deus que você tem um grande problema, diga sim, para o seu problema que você tem um grande Deus."
