To permit other forms of authentication to be performed, having the generic set-up of the user and verification in a common class allows this implementation to be called via alternative authentication methods. These changes have been migrated from DatabasePubKeyAuth into SshUtil, with the only changes being from the required signatures and a modification which doesn't require a key for the authentication or success stage.
