[Fiware-creatifi-coaching] [CreatiFI Benelux Hub] FIWARE Lab IDM issue

[Andrea Maestrini]

Dear FIWARE coach,
we received an updated from a CreatiFI applicants.
Thanks in advance.

*****************************
What I understand from the instructions on the github link you provided is:

   - *not* that the *body is incorrect* as you suggested?!
   - but the *current FIWARE IDM implementation does not support the
   *grant_type=client_credentials* anymore*: *"Currently we support two
   grant types, the Authorization Code Grant and the Resource Owner Password
   Credentials Grant."* Correct?

So in short with the current FIWARE Account IDM it is not possible to
perform Application/Service to Service Calls Using Client Credentials (not
user)? *I just want my applications to authenticate itself*, it does not
have a user defined but I just want to be sure the application is allowed
to use my backend api's.

So the video instructions I followed on [[
https://edu.fiware.org/mod/page/view.php?id=235]] are not valid anymore for
the current FIWARE Account IDM implementation? Or am I mistaken?

Best regards,
Jan
