As far I know, all this should work as you would expect. Quite recently,
Andrew Bartlett and I went about testing some of the behaviour of the
KDC and confirming behaviour such as RODC ticket forwarding.
The one thing to check would be whether or not Samba is being linked
against system Heimdal. As it stands, there is no real testing of Samba
using system Heimdal and from the testing we've done, there are almost
certainly oddities and unexpected failures with this setup - this included.
