Essential Attribute Bundle

IdPs are encouraged to release the essential attribute bundle to the broadest class of SPs possible (subject to policy):

If your deployment of eduPersonPrincipalName is non-reassigned, and your IdP releases the essential attribute bundle to all SPs, then your IdP supports the Research & Scholarship Category as a side effect, without further configuration.

It is straightforward to configure a Shibboleth IdP to release the essential attribute bundle to any SP.
