No, you don't have a single point of failure, this is why I mentioned
using ktutil (well, I said ktadmin, my bad).  You merge the keytab for
the machine with the keytab for the HA user.  This way the clients are
able to both auth to the HA and to the the underlying machine.  It is
what we do, it works fine.
