It's a good idea to separate the files required for bind. However, it has
to be done carefully.
For dlz_bind module, provisioning creates a partial copy of samdb with base
partitions. But the dns partitions are linked to the dns partitions from
the main samdb.
For named, to be able to access the dns partitions in private directory
(via a link in
the separate bind_dns directory), the private directory needs to have at
permission for others. That will indicate that you can change the
the private directory to 0751 (or 0701 if you must).
The other option could be to move sam.ldb* out of private/ directory into
directory. That way private/ can be 0700. We still need to manage the
for sam.ldb* files and the directory they are moved in, so named as the
