Any pointers on how to find out current backend used by an installation?
We don't have an interrogation mechanism and the runtime behavior is to
mostly indistinguishable, but on Linux or similar you can use OS
mechanisms. ldd on libk5crypto.so.3.1 should show a dependency on
libcrypto, nm should show dependencies on EVP functions, and sotruss on
kinit or kvno should show calls into libcrypto.
