Note however that most of these things are not classified as errors, so they are logged at LOG level. It may be that you're filtering so you're not showing LOG level information, or perhaps your syslogd is configured to write them to a different file. AFAICS, the only code-path that does not log *why* it rejected the authentication is the case when the client refuses to send a password. //Magnus
