It's my understanding that these are not "hints", but canonical
declarations of the service principal name to use.  If Samba is wrong
in what it's sending (which is possible, though it should also be
possible to catch this at runtime based on the available credentials),
there are certainly cases in a moderate-sized AD forest where it's
*impossible* for the client to determine a valid service principal for
the server.
