I have done a application which I have registred in fiware, this application only have one authorized user to use. I want to authorize more users with new roles to they can use it. I am trying to give a role for an user without use the graphical interface whit keystone api, but nothing works. I am looking for in a lot of pages but I don´t find nothing. I find this page https://github.com/ging/fi-ware-idm/wiki/REST-API only, where I saw Roles API. I have tried to use, but it didn´t work.
If I use, PUT /OS-ROLES/users/$user_id/applications/$application_id/roles/$role_id
Result, {"error": {"message": "You are not authorized to perform the requested action: identity:add_role_to_user_default_org", "code": 403, "title": "Forbidden"}}
I don´t understand the result because I am the owner of the application. How I can solve it?
Thank you
