title: Authentication and authorization of FHIR server
body: <p>I have spinned of a azure service for fhir. I want to use it with a .NET core API and I want to control the authentication and authorization inside the API. I haven't found an example where I can authenticate the webapi in azure without prompting for username and password with clientid, client secret and tenantID. And also regarding authorization, is there a way to restrict a tenant to only access certain group of patients with FHIR ?</p>
