Perhaps more importantly, while these libraries have similar names, they
don't have identical ABI's, and they don't speak even remotely the same
protocol. If one needs to be able to perform administrative operations on
both Heimdal and MIT KDC's, one needs both libraries.
I would note that there's no reason a library libkadm5clnt.so can't have an
soname like libkadm5clnt.so.7_mit or some such (and similarly for Heimdal).
For various reasons I have one named libkadm5clnt.so.4_opensc2 and it works
