Hi Fabian,

Effectively , successful connections are from the mclient.

My perl is pretty much non-existant.  However, it looks as if you *do*
specify that you want to use a database, "demo" in this  case.

Merovingian here sees no database requested.  The other successful calls
in this log snippet are from mclient or something?
