SIR Service Providers
Any application supporting OpenID is accessible through SIR. Registered applications can also receive additional attributes, according to the applicable attribute release policies.
OpenID is an open, decentralized standard for user authentication and access control, allowing users to log onto many services with the same digital identity.
OpenID provides an interesting choice for integrating off-the-shelf applications already supporting it into SIR, as well as to support those applications that require their own account management systems. The SIR team has prepared a Guide to OpenID-based Integration.
