There is a bug: https://bugzilla.samba.org/show_bug.cgi?id=14535

Basically, there is no code to create the keytab in the bind-dns 
directory. The code is only required on three occasions, when a new DC 
is provisioned with '  --dns-backend=BIND9_DLZ', when you upgrade from 
the internal dns server to bind9 and when you join another DC with 
'--dns-backend=BIND9_DLZ'. The code is there for the provision and in 
samba_dnsupdate, but not for the join.

The fix (at the moment) is to change to the internal dns server with 
samba_dnsupdate, then change back to bind9 with the same tool, the 
keytab will then appear in the bind-dns directory.
