Problemas instalação Bind9 em conjunto Samba 4 como AD

[emersoncpaz]

Prezados,

Estou tentando configurar o Samba 4 como AD num servidor Ubuntu 12.04 LTS. Utilizei diversos tutoriais como referência e todos chegam no mesmo ponto: Não consigo iniciar o Bind9.

No syslog fica a seguinte mensagem:

Entendo que o problema está na linha: samba_dlz: Failed to connect to /usr/local/samba/private/dns/sam.ldb

Alguém já passou por isso?

O Samba utilizado é a versão 4.0.9.

Esse arquivo existe?

O usuário que roda o bind (named:named) tem acesso a ele, em todo o caminho?
