That's interesting - what I meant is that Windows and Samba4 (Heimdal)
accepted the 3.0 behaviour, where we had the normal krb5 checksum type,
and no data (because it's not gssapi, so no bindings to sum). The
variations after that I'm less clear on.

I would like to work with you on this, if you are able.
