As I understand it, the buffer overflow fix is what broke it.  The first
analysis that I read indicated that it rendered the kaserver incapable of
handing out service tickets; at the very least, it does severe damage to
its ability to serve as a functioning K4 kdc.

Better, maybe, but it's a major undertaking if you've already got a large
K4 realm.  We've been trying to line up all the ducks for that switch for
the past four years or so (admittedly a good chunk of that time was wasted
on DCE, which I'll be happy if I never see again).
