7. EBSCO have recommended customers to contact their federation for the required attribute configuration. For the UK federation, first ensure that your identity provider releases an eduPersonScopedAffiliation (ePSA) value of "firstname.lastname@example.org" (where "xxx.ac.uk" is the scope for your organisation) to the EBSCO SP.
Then go to EBSCO's online customer administration system (EBSCOadmin), select the "UK Higher Education" region, go to the "Shibboleth" configuration tab, ignore the "Shibboleth Entitlement" field and in the "Shibboleth Affiliation" field enter email@example.com. If you are not already familiar with EBSCOadmin then EBSCO customer support may be willing to make these changes on your behalf.
