[Samba] Logging successful log-ins

There's a note at the top of that document:

"Samba only supports logging of succeeded authorization events."

Does that mean that it won't log authentication events at all? Because that's implied.

I think it would be better, assuming it will log auth events, to say;
"Samba only supports logging of *successful* authorization events, not unsuccessful. Samba also supports logging of both successful and unsuccessful auth events."

Just my two bits worth.
