Rest service without userrole

I've been trying to deploy a simple REST service that can search for a product much like in the recent webinar about this subject. The problem i'm having is that I want the service to be avaiable for all users (no login), but when I set the SecurityRole attibute in the microflow "CreateMicroflowService" to "User" it still asks for authentication when i try to acces the rest service. Am i doing something wrong? Or is there a way for me to specify that every userrole can call this service? thanks.

Use '*' for user role.
