[Samba] Samba + BIND9 DLZ. DNS dosen't resolve FQDN, only short hostname

Well, finally I found the recommendations against .local here:


However, still, the originating wiki should AFAIK be more verbose.


For now it only says "Make sure that you provision the AD using a DNS
domain that will not need to be changed. Samba does not support renaming
the AD DNS zone and Kerberos realm. For additional information, see
Active Directory Naming FAQ."

I wish this would indicate somehow, that some TLD's are very problematic
and strongly discouraged. I took this notice like this: "I'm sure I
won't need to rename, so I don't need to read the Additional information
on AD Naming."
