Forbid public access to DNS tree
With a publicly accessible DNS tree in LDAP, anyone with an access
to the LDAP server can get all DNS data as with a zone transfer
which is already restricted with ACL. Making DNS tree not readable
to public is a common security practice and should be applied
in FreeIPA as well.
This patch adds a new deny rule to forbid access to DNS tree to
users or hosts without an appropriate permission or users which
are not members of admins group. The new permission/aci is
applied both for new installs and upgraded servers.
bind-dyndb-ldap plugin is allowed to read DNS tree without any
change because its principal is already a member of "DNS
Servers" privilege.
