ipa-dns-install now uses LDAPI/autobind to connect to DS during the setup of DNS/DNSSEC-related service and thus makes -p option obsolete. Futhermore, now it makes more sense to use LDAPI also for API Backend connections to DS and thus all forms of Kerberos auth were removed. This fixes https://fedorahosted.org/freeipa/ticket/4933 and brings us closer to fixing https://fedorahosted.org/freeipa/ticket/2957 Reviewed-By: Martin Basti <mbasti@redhat.com>
