This training materilas is provided for the AAI training during EOSC-hub week 2019, 12 Apr 2019, Prague. This material provides an overview of the various integration workflows in support of resource providers’ needs for federated access through the EOSC-hub AAI. These workflows build on standards and open technologies, including SAML 2.0, OpenID Connect, and OAuth 2.0, in order to support the integration of web-based services. The training also covers more advanced workflows for addressing non-web-based access use cases (e.g. command line and API). In this context techniques for obtaining credentials on behalf of the end-user using OAuth tokens and X509 proxy certificates through online authorities will be presented.
