--- Comment #19 from Iain Morgan <imorgan at nas.nasa.gov> ---
This looks like a client-side issue to me.

The client logs indicate that no host based authentication packet was
sent.  Since EnableSSHKeysign is set in the ssh_config, this probably
means that the permissions are incorrect on either the ssh-keyskgn
executable or the private host keys.

Note that on Red Hat, ssh-keyskgn is normally setgid to group ssh_keys,
and the private keys are expected to be readable by that group. 
Whereas, stock OpenSSH expects the private keys to be readable only by
root and thus ssh-keyskgn should be setuid root.
