Forgot to answer the "what does it do part". Long ago it was realized
that on insecure operating systems with insecure file systems you did
not want to store authentication credentials in a file. You want to
store them in memory so they go away when the machine is turned off.
So Kerberos stored the credentials in a shared memory block so all
applications could access it. However, if no applications are using
the shared memory, the OS releases it. So there always needs to be at
least one application using the shared memory. That one application is
Fleavius. However, in the last few years the architecture of in memory
storage has been changed and recent MIT KfW distributions use a
different process: krbcc32s.exe
