Cloud Identity

We are building a IAM service to generate and authenticate/authorize client requests via the client_credentials flow. We are using Microsoft Identity Platform (V2) to generate tokens with a default scope (./default) and subsequently trying to authenticate and authorise the API Permissions. We are unable to do so as the generated token does not have the scope/roles claim and gets rejected by the passport-azure-ad Bearer Strategy module.

Can anyone tell me what steps am i missing.

Thanks in advance.

    anonymous user, Thank you for reaching out. The first thing to note here is, the both roles and scopes are not available together in a token, the reason being, roles get listed when you use the client_credential flow of OAuth along with adding Application Permissions on the App Registration. Similarly, scopes get listed in the access token, when you use OAuth flows like Authorization_Code Grant Flow or Implicit Flow etc along with adding the Delegated Permissions on the App Registration.

    In this case, since you are using Client_credential flow of OAuth, I would recommend you to check and confirm if you are using Application Permissions along with Admin Grant on them. As if the application permissions are mission, you would miss them in the token too under the scp key (scope).

    Hope this helps.
