Squidguard não está funcionando.

William Martins

Olá pessoal!

Estou com problema para fazer o squidGuard funcionar no PFSense 2.4.4 (p1, p2 e p3).

O squid está funcionando perfeitamente, porém quando eu integro com o squidGuard ele não bloqueia nada. Está autenticando no AD normalmente.

Em Common ACl eu bloqueei tudo, para testar, depois crio as regras para liberar alguns sites. Acho q deveria bloquear o acesso a qualquer site independente de quem autenticou.

Já reinstalei várias vezes o PFsense.

Segue as configurações do squid e squidGuard.

O problema esta com o LDAP, pq configurei o proxy transparente e o squidGuard respeitou as regras.

William Martins

Resolvido.

No meu caso era a senha que setei no LDAP do squidguard. Não pode ter caracteres especiais... Estava testando com Administrador. Criei um usuário e coloquei a senha 123456, tbm nao serviu (acho pq é muito facíl) mudei para uma alfanumérica e funfou...

Mas dei mole, coisa de quem é faixa branca ainda kkk, se tivesse ido desde o inicio no log acharia o problema rapidinho....
