Hello Paul,

Thanks for your report

Currently there is no way to build using system Heimdal, the embedded
copy has diverged too much from upstream I believe.

Maybe a fix would be to switch to MIT Kerberos, see #726459. I'm
hesitant to do this given the risk of this big change (and some people
probably use Debian for the features that don't have parity yet).

Andrew, is there any chance to sync Heimdal code with upstream? Or
should we switch to MIT?
