This page will list all the SAML2 attributes that SURFconext and their Identity Providers identity providers have to offer. An attribute is a characteristic that describes a user. It is a 'name:value' pair. The attributes included in the SAML assertion correspond to certain attributes a service provider needs to work properly. In general they are needed to:

  • Convey user information from the Identity identity provider or (IdP) to the service provider (SP)
  • Create an account for the user at the service provider
  • Authorize specific services at the service provider

Now, when a user logs in to a Service Providerservice provider, SURFconext sends a SAML assertion to the Service Provider service provider via the browser of the user, that contains a:

  • User identifier. Al All services receive these and are either a configurable Transient or Persistent NameIDtransient or persistent NameID (chosen via SP Dashboard).
  • and Additional attributes. These are optional and differ per Service per service.


Note

SURFconext's SAML2 implementation adheres to the SAML2int standard 0.2.1.

The header on the link above states that work on saml2int has moved to Kantara Initiative. Until further notice, the SAML2int standard SURFconext adheres to remains at 0.2.1. remains at 0.2.1.

Note
titleContent provider?

For content providers, SURFconext (in consultation with the partnership of the Dutch university libraries and the Koninklijke Bibliotheek (UKB), Hogeschoolbibliotheken (SHB)) applies a separate attribute release policy. The following are allowed:

  • Persistent or transient NameID
  • schacHomeOrganization
  • eduPersonAffiliation

Read our blog for more information (Dutch)

Info

Before you start digging into the theoretical stuff on this page, you might want to start with our 'best practice' page for an introduction to and how attributes are best used.

...

Warning
titleRemark

The NameID and eduPersonTargetedID,  which which is basically a copy of the NameID, when set to persistent is unlikely to change and very privacy aware but can change when service providers or identity provider make critical make critical changes. This can cause user profiles for services to be lost. The NameID, as used in the SAML assertion to a service provider when loggin' on, is generated using the uid, schacHomeOrganization, the Entity ID of the service provider together with a secret that uses a SHA algorithm. Institutions or services that are in production and change one of these attributes, will cause a new NameID and eduPersonTargetedID to be generated by SURFconext when doing so. This can cause loss of access to profiles at services. We will notify identity providers and service providers when we see a change in one of these attributes to prevent user data being lost.

Description

The unique code for a person that is used as the login name within the institution.

Examples

flåp@example.edu (See note below)

Notes

  • The uid is not a unique identifier for SURFconext users.  Uid values are at most unique for each IdP.
  • Ideally the uid is not only a login name/code but also an identifier that is guaranteed as being unique within the institution over the course of time. At the moment, there is no such guarantee.
  • Use the NameId for unique identifiers in SURFconext rather than uid.
  • Use the eduPersonPrincipalName attribute if a human-readable unique identifier is required
  • A uid may contain any unicode character. E.g., "org:surfnetsurf.nl:joe von stühl" is a valid uid.
  • SURFconext translates @-characters in the uid to underscores before constructing the NameID. flåp@example.edu translates to flåp_example.edu.

Notes

  •  In the past, SURFconext used to send the home organization in the attribute urn:oid:1.3.6.1.4.1.1466.115.121.1.15, which was incorrect.  Since 2013, the correct oid urn:oid:1.3.6.1.4.1.25178.1.2.9 is in use.  For reasons of compatibility, the old (wrong) key is still sent.  It will be removed in 2020the near future.
  • Matching values against this attribute should be case-insensitive, i.e. the values "uniharderwijk.nl" and "UniHarderwijk.nl" should be considered equal. For Interoperability reasons however we require lower-case values as specified above in SURFconext.
  • It is desirable to have the same value for all your users.
  • SURFconext will store the allowed value for your institution in our configuration so we can check that no illegal values are being sent.

Data typeUTF8 String (only the values enumerated below are allowed)

Description

Indicates the relationship between the user and his home organization (institution). The following values are permitted within SURFconext:

  • student — A person enrolled at an institution, an external student or course participant.
  • employee — A person with a position at or labor agreement with an institution.
  • staffAll academic staff and teachers. (deprecated; do not use in new deployments)
  • faculty — A person whose primary role is teaching or research. (Commonly called WP at Dutch universities. Please note, PhD students are also perfectly allowed to carry this value.)
  • member — Anyone that holds at least one of the above affiliations is also a member.

  • pre-student — A person who has registered to start studying, but is not yet a full student. See this page (Dutch only) for more information about pre-students and the terms and conditions under which such users are allowed access. Pre-students will never be allowed access to service providers without prior consent from the service provider.
  • affiliate — A person who is authorized by the Institution, pursuant to the lenience model concluded by the Institution, to use the Service.

Use Note: only the above mentioned values are allowed within SURFconext. Use the definitions mentioned to determine which affiliation a user gets. If the definitions are not sufficientyou have doubts whether a user (fully) fits the definition, please use common sense.

Examplessee above

Notes

  • Any user who has the affiliation student, employee, or faculty, should also have the value member.
  • Identity Providers might internally use additional values for the affiliation attribute, such as alum. Per SURFconext policy, the IdP may not allow such users to access SURFconext.
    Other values mentioned in the eduPerson specification include library-walk-in. This value is not currently used within SURFconext.
  • According to the eduPerson specification, the values of this attribute are case insensitive; for Interoperability reasons however, we require lower-case values as specified above in SURFconext.
  • The document REFEDS eduPerson(Scoped)Affiliation usage comparison is useful to determine the usefulness of values in an international context.

Data typeUTF8 string (unbounded)

Description 

The attribute eduPersonTargetedID is a copy of the persistent Subject -> NameID, which is generated by SURFconext itself. When an Identity Provider provides the eduPersonTargetedID itself, it is always overwritten by SURFconext. 

Examplesbd09168cf0c2e675b2def0ade6f50b7d4bb4aae

Notes 

This attribute is created because the Subject -> NameID itself is not part of the SAML v2.0 response attribute list and therefore only is available for an application if the local SAML implementation explicitly supports this. Within SURFconext the Subject -> NameID is explicitly copied into the eduPersonTargetedID attribute, including XML, in order for the identifier to be used like any other attribute, but only when NameID is configured to be persistent (as the eduPerson definition of eduPersonTargetedID requires it to be persistent)

Assertion by the home institution about specific aspects of identity proofing or authentication strength. Although in principe any URI is allowed, SURFconext recommends to populate this according to the standards as outlined in REFEDS Assurance Framework. The institution needs to match their identity management practices to this standard to know what values it may assert. This provides ways to communicate properties about e.g. identity proofing or identifier lifetimes, for interpretation by SPs. SURFconext itself does not do anything specific with released values
