[Samba] Log levels

[Chris St. Pierre]

I have been asked to configure out Samba installation to log at least
two types of information:

1.  In order to be HIPAA-compliant, we need an audit trail of who
    accesses what documents and folders.

2.  For internal use, we need an audit trail of who creates/deletes
    what documents and folders.

What is the _minimum_ log level that will give me both of these,
without filling up my disk?

Thanks!
