Ultimately it is up to the identity provider and service provider to agree on a set of attributes to be released by the IdP, SURFconext only mediates. However, it is strongly recommend to stick to the above attributes as they are standardized and ensure greater interoperability.
The table below lists the attributes that have been defined for use within SURFfederatie. This list was created in consultation with the connected institutions, specifically within the 3TU partnership. With a view to the expected future international collaboration, this table is largely based on the EduPerson and SCHAC tables. A number of attributes that are specific to SURFfederatie and the Netherlands have been added.

Note that the attributes described on this page are the standardised attributes that an identity provider may provide to the SURFnet federation gateway. If you are a service provider connecting to SURFconext, please refer to the attribute description on ?Authentication using SAML page. |
