Sadly normal.  Ideally we would rotate those, and the krbtgt password,
but currently we don't do that.

Rotating DC passwords only, even if not the krbtgt, would be worthwile,
but only if you can coax the DC into doing NTLM authentication
outbound, but that isn't normally the case.

But we really need to do both.
