  3. Proxy IdP
    Initially a new authentication provider for the existing
    EduCloud SSO pilot-instance, later will replace it
    – Up to the production operator to decide between one “big” proxy or a
    set of proxies (e.g. social proxy, strong authn proxy, etc)
    Developed by CSC, running in Pouta cloud
    Based on Shibboleth open source software
    – Co-operation with the Finnish Population Register Centre’s national
    proxy implementation project

  6. Authentication Selector Service
    Needed for linking the existing student ID (oppija ID) to
    a user-selected authentication method
    – Invitator: e.g. teacher, secretary
    – Invitee: student, who can select his preferred authentication method
    Specification for the first version has been done
    – Web UI, supporting invitation via email or “live”
    Back-channel API will be developed later, if needed
    – Invitator & invitee authentication via IdP proxy (SAML)
