Question:
How to properly configure IoT sensors in order to gain authentication and authorization using IdM Keyrock and Wilma PEP Proxy

Description:
I have being working for some weeks with the IdM Keyrock, Wilma PEP Proxy and AuthZForce in the context of Fiware Platform, in order to develop an IoT application.

I had success in protecting the Orion Context Broker APIs using Wilma PEP Proxy and now is the turn to protect IoT-UL APIs in order to secure "southbound" APIs.

I thought about using a similar strategy to that followed with the Orion Context Broker. In this case each sensor has an OAUth2 token and putting a PEP Proxy in front of the IoT-UL APIs I would be able to authenticate and authorize every request to them.

Then I noticed that into the Keyrock interface, there is a section inside my Application tab where I can register IoT Sensors so I registered a few IoT sensors. Then I realized that I could not assign roles to this users (because internally they are users) and I could neither login using keyrock interface. So I Could not assign roles and neither generate OAuth2 tokens.

What am I missing? Perhaps authentication and authorization is not yet available for IoT sensors. In that case I thought about using regular users to represent IoT sensors but I think that is overkill. Any help with this would be very usefull.
