I would caution you that if you are targeting MacOS X as a platform, one
of the most important things is integration with the native credential
cache format (especially if you are assuming your credentials are being
acquired as part of the single signon process).  On MacOS X the default
credential cache uses a RPC mechanism to talk to a daemon process (and
that has actually changed to a DIFFERENT RPC service in more recent
versions of MacOS X).  My brief look at gokrb5 suggests that it only
supports the FILE credential cache type.
