Dear Jeff, Thank you for your very instructive answer. I realized that I was only at the half of my journey though the credential system (and the config system also). I'm still struggling with the manager-core helper that doesn't want to prompt me anything and persist to return blank user and password despite the fact it has no idea of the real values, but this is another story.
