    Buenos Dias,

    He tenido serios problemas con el Squid y la autheticacion con AD he tratado muchas cosas y nada parece funcionar, logro que el pfsense se authetique utilizando el AD pero cuando vamos a la parte de lograr que el squid funcione el a historia es diferente el squid cuando coloco  en modo transparente functiona perfecto, pero cuando le habilita la configuracion oara que filter basado en usuarios de la red siempre la misma respuesta, solicita el usuario y el password 1000 veces.

    aqui les coloco el archive de configuracion para ver si tienen alguna respuesta a esta duda, el seguido los tutorials y nada

        Como dice rocaembole, es la mejor solución, yo lo tengo funcionando en un ambiente de aprox 200 usuarios y funciona casi a la perfección. Te recomiendo seguir este tutorial: https://www.youtube.com/watch?v=C84EJcrwEvg
