[FUG-BR] Squid autenticado no AD.

[Adiel de Lima Ribeiro]

Pessoal, bom dia.
Tenho o Squid autenticado no AD, tudo funciona normalmente, mas alguns
sites simplemente ficam pedindo senha toda hora e não funcionam, para
máquinas fora do domínio, não adianta entrar com credenciais, fica
pedindo senha toda hora, alguém tem uma luz?
Obrigado.
