[Fiware-finodex-coaching] Assign roles to a user via Keyrock API

[Jesus Barrera]

Hello,

Some weeks ago we send a question to Stack Overflow but no response has 
been received 
(http://stackoverflow.com/questions/31340155/give-role-to-user-for-application-registred-in-fiware).

The problem is that we have an application registered by an user in 
FIWARE Lab and we want to allow other users to use the application. For 
this purpose we want to assign them their appropriate roles via Keyrock 
API. We have tried to use the following method:

PUT /OS-ROLES/users/$user_id/applications/$application_id/roles/$role_id

(http://docs.keyrock.apiary.io/#reference/keystone-extensions/role-user-relationship/assign-a-role-to-a-user)

However, we obtain the following error message:

Result, {"error": {"message": "You are not authorized to perform the 
requested action: identity:add_role_to_user_default_org", "code": 403, 
"title": "Forbidden"}}

Can anyone help us?

Thanks in advance for your help.

Regards,
Jesús
