You can make the separate logger to work with a couple of modifications. 
Update your existing separate Log clause like this:

     Identifier authby-not-used
> <Log FILE>
>      Identifier PASSWORDLOG
        Trace 3
>      Filename %L/%Y%m%d_password.log

The default Trace value for a <Log ...> clause is 0 (ERR). You'd either 
need to call log with LOG_ERR or set Trace to 3 (INFO) as shown above.

I also suggest wrapping the Log clause within an AuthBy or Handler (such 
as <Handler Notused=1>) that is not expected to be used for processing 
any requests. The reason is that any top level <Log ...> clause will log 
all log messages. A logger within a clause is specific for the enclosing 
clause. It's not pretty and that's why I called this method "arrangement".

Happy password hunting. Please let us know if the above solves the problem.
