I'm currently using the KFW 4.1 build from MIT. I've tried building it
myself but it requires a very old toolchain (which defeated the point of
what I was trying to do at the time).
I haven't yet looked to see if the source for krb5-1.8.2 will build or even
has the right bits in it for Windows - as I'm sure you know MIT seem to
maintain an entirely different version for Windows for which I assume
there's a reason.

Fixing the config on hamerkop should deal with that I think. Though I am
confused as to why the Buildfarm UI thinks it has Kerberos support enabled
- did we change the config parameter from krb5 to gss some time prior to
9.5? If so, that could explain it.

Right, I imagine so. It's on my todo...
