An Identity Provider supports the R&S category if, for some subset of the Identity Provider’s user population, the Identity Provider is willing and able to release the R&S attribute bundle to all R&S Service Providers without administrative involvement, either automatically or subject to user consent.
The R&S attribute bundle consists of the following attributes:
- sn (surname)
Any other attribute listed in Service Provider metadata is out of scope with respect to this specification.
An Identity Provider that supports the R&S category MUST be willing and able to release all R&S attributes to all R&S Service Providers. The only exception is the eduPersonUniqueId attribute: If the Identity Provider’s deployment of eduPersonPrincipalName is non-reassigned, release of eduPersonUniqueId is strictly OPTIONAL.
- By unconditionally releasing the complete R&S attribute bundle to all R&S SPsService Providers; OR
- By conditionally releasing attributes from the R&S attribute bundle based on the
<md:RequestedAttribute>elements in Service Provider metadata.
- , regardless of whether the optional
isRequiredXML attribute is (or is not) present.
The following practice should be followed for persistent identifiers:
If a Service Provider lists the eduPersonPrincipalName attribute in metadata, and the Identity Provider's deployment of eduPersonPrincipalName allows for reassignment, then the Identity Provider MUST release both eduPersonPrincipalName and eduPersonUniqueId to the Service Provider regardless of whether eduPersonUniqueId is listed in metadata.
If a Service Provider lists the eduPersonUniqueId attribute in metadata, and the Identity Provider’s deployment of eduPersonPrincipalName is non-reassigned, the release of eduPersonUniqueId is OPTIONAL despite its being listed in metadata.
Any non-R&S bundle attribute listed in Service Provider metadata is out of scope with respect to this specification.
6. Attribute Release
Identity Providers are strongly encouraged to release the following bundle of attributes to R&S category Service Providers:
