This is thrown if the authentication is valid, but is not enough to

"""
Raised by public key checkers when they receive public key credentials
that don't contain a signature at all, but are valid in every other way.
(e.g. the public key matches one in the user's authorized_keys file).
Protocol code (eg
L{SSHUserAuthServer<twisted.conch.ssh.userauth.SSHUserAuthServer>}) which
attempts to log in using
L{ISSHPrivateKey<twisted.cred.credentials.ISSHPrivateKey>} credentials
should be prepared to handle a failure of this type by telling the user to
re-authenticate using the same key and to include a signature with the new
attempt.
See U{http://www.ietf.org/rfc/rfc4252.txt} section 7 for more details.
