[rules-users] Drools Flow - users authentication.

Hello, I want to try Drools Flow software (Eclipse plugin works). I have installed Guvnor. Then I have installed console (two wars). I type http://localhost:8080/gwt-console/app.html in my web browser. Then I get a dialog, and I have to authenticate. But I don't know default Username and Password. As far as I know, I have to create a XML file, and manually create a user and his pass... Am I right? I use Drools Flow Console v.2.1. Please help me, and do it slowly and like for no-IT person ;) Thanks, tom.
