smbtaquery -C is currently interactively asking the user to enter the information required to access the database. It should first take a look into the configuration file and check if there are already connection informations available. If so, it should ask the user if it should use this, if not it shall fallback to the current behaviour.
Michael maybe you have time for this?
Yep, I'll dig into it next week.
Due to the fact that the convert function will be moved to smbtad, and it will fully automatically convert, this bug ends as invalid.
