[Samba] Possible small bug discovered in Samba4 dc sernet + bind9 (Debian)

[Oscar Aparicio Holgado]

Hi all.
I have installed sernet-samba-ad success with bind9 from Debian repositories.
I added:
tkey-gssapi-keytab "/var/lib/samba/private/dns.keytab"; in /etc/bind/named.conf.options
and then i added:
include "/var/lib/samba/private/named.conf"; in /etc/bind/named.conf.local
After doing this two steps and modified /etc/resolv.conf when you restart bind9 it says error "unable to read /etc/bind/named.conf.local, access denied" Some of the files have root:bind permissions, but /var/lib/samba/private folder have this permissions:
drwxr-x---   7 root root      4096 mar  5 23:20 private
And with this config bind is unable to read some files in that folder, possibly in dns folder.
if i change the permissions as this:
drwxr-xr-x   7 root root      4096 mar  5 23:20 private
Then now you can restart safely bind9 and no more errors of denied files. Would you please confirm this small bug?

Thanks all.
