One such challenge is the integration of authentication and authorization among different systems. In this publication, we describe the development of a software as a service solution with the focus on the integration of authentication and authorization. For the development of the business logic, the integration platform as a service MuleSoft is used. The identity and access management as a service solution Okta is used to provide the necessary means for authentication.
