Seeing some more activity on this.  It appears that while most command names 
are basically the same, the options are not the same between MIT and Heimdal. 
  I don't know details.  I suppose that will just have to be user beware.

Also libraries have different sonames:

MIT:
/lib/libkrb5.so.3
/usr/lib/libkadm5clnt.so -> libkadm5clnt_mit.so
/usr/lib/libkadm5clnt_mit.so.7
/usr/lib/libkadm5srv.so -> libkadm5srv_mit.so
/usr/lib/libkadm5srv_mit.so.7

Heimdal:
/usr/lib/libkrb5.so.26
/usr/lib/libkadm5clnt.so.7
/usr/lib/libkadm5srv.so.8

So I think use of %{_libdir}/heimdal is going to be a must.

I really know little about the inner workings of either unfortunately.  Any 
help on this is appreciated.
