Problema em integrar Dansguardian com squid 3 + NTLM.

[brottor]

Eu tenho um ambiente de rede (squid e dansguardian) que funciona sem NTLM, começamos a implementar NTLM e surgiu alguns problemas, detre eles um eu não consigui resolver. Quando acesso a conta do yahoo mail, após um minuto ou dois, aparece uma tela de login, acontece somente com windows XP, em maquina com windows 7 funciona perfeitamente. Descobri depois, que conectando apenas no squid também funciona normal. Logo acredito que o problema é como o Dans está passando as requisições pro Squid. Alguém já teve esse problema? ou algo parecido?
