What would really help is if someone went through the "things"
that Samba does, and comes out with a list of "user loggable"
events, such as "user logged on", "connection dropped", "connected
to share" etc. If the list were small enough (i.e. so it didn't
turn into a parallel debug system) we could then instrument
the code at these points, then emit event-log records that
were readable by the Windows event log viewer (or a UNIX
equivalent) - or even to a separate "user events" log file
(or syslog).

It would have to be a limited list, and not include IO
events (opening file, read file etc.) as these are better
handled by the audit modules, or when we add the audit ACLs,
the audit ACL logging.

Someone from HP (not mentioning any names here but he might
remember who he is :-) did promise a couple of years ago at
SambaXP to do this, but I'm guessing he didn't have time.

If someone came up with this I'd certainly help push it
into the code.
