It is unlikely, as Dovecot isn't compiled against Samba components, as
far as I know.
What it does mean is that in that file, some parts are now under #ifdef
and used only when building against Heimdal.
It means what everybody involved in the Kerberos porting dev work
knows, that switching between the Kerberos libraries is hard work, and
that a 1-to-1 match isn't possible in all places. That is why the MIT
build project isn't finished, and why it will continue to take
I realise this makes the hope of distribution packages of the AD DC
from Red Hat or SuSE a long way off, but that is the reality of the
firm positions taken.
