Centrify Express es una completa suite de software libre que permite: unir clientes GNU/Linux,Unix o Mac a un dominio de Active Directory, intercambio de archivos, vigilancia y seguridad en la nube para los sistemas multi-plataforma. Es la solución más rápida y más probado para la integración de UNIX, Linux y Mac con Windows, y ofrece una mayor funcionalidad.
Antes de instalar nada vamos a preparar el cliente para que pueda acceder a nuestro controlador de dominio.
Para ello modificamos el fichero /etc/resolv.conf
bash
cat /etc/resolv.conf
domain cdp.redorbita.com
search cdp.red-rbita.com
nameserver 192.168.1.142Nuestro direccionamiento IP:
text
tail -n5 /etc/network/interfaces
iface eth0 inet static
address 192.168.1.141
netmask 255.255.255.0
gateway 192.168.1.142También comprobamos el fichero /etc/nsswitch.conf. el cual tiene que contener algo así:
bash
cat /etc/nsswitch.conf | grep -i host
hosts: files dnsUna vez configurado comprobamos que llegamos por nombre.
bash
ping redorbita.com
PING orbita.com (192.168.1.112) 56(84) bytes of data.

Accedemos a la web official de Centrify y descargamos el cliente correspondiente con nuestra distribucion GNU/Linux (O Unix), y arquitectura.
