I think we need to deprecated that first.

Yes. The question is how to store the keys.
Is there a way to disable DES on Windows, so that we could
check what they store in the Primary:Kerberos-Newer-Keys
and Primary:Kerberos blobs in that case.

I think we need to keep that, because not every account
has aes keys, as the password might not be changed.
