If you want to use OpenID Connect you will have to make sure your software supports this protocol. Several software products already support OpenID Connect out of the box. If your software is amongst these, you can continue to to the paragraph about Claims and attributes below.
We strongly advise you not to build your own OpenID Connect implementation, but use one of the products already available. The official OpenID website provides a nice overview of certified and uncertified implementations.
Claims and attributes
Most services require extra information about the authenticated user, such as a name, email address or affiliation. In OpenID Connect (OIDC), this extra information comes in the form of claims, whereas in SAML, claims are called attributes. In SURFconext, the user authenticates at his Identity Provider (called OpenID Provider in OIDC) - this all happens using SAML. SURFconext translates the incoming SAML attributes to OIDC Claims and provides them at the userinfo endpoint for your Service Provider (called Relying Party in OIDC) to consume. Read this page to see which claims are available for use within your service.
SURFconext has a data minimisation policy, which means you only receive those claims that are strictly needed to make your service work.
Once you have implemented OpenID Connect in your application and you want to start testing, you can connect to the SURFconext Test environment.
