--- Comment #6 from Iain Morgan <imorgan at nas.nasa.gov> ---
Looking at the debug output more closely, it looks like the client is
not attempting to use any certificates. The server logs just three
hostbased authentication attempts, and the 'Failed hostbased' messages
all indicate that these were plain keys.

As an aside, it probably isn't a good idea to create certificates for
all the supported key types. In most cases, just one (or perhaps two)
certificates should be sufficient. Since hostbased will try all host
keys and certificates until it succeeds, you could easily exhaust the
allowed number of authentication attempts if the ssh_known_hosts or
shosts.equiv files are misconfigured.
