InAcademia leverages the eduGAIN interfederation, acting as a proxy service to services that need only validate the academic affiliation of a user. Offering InAcademia via your Federation offers a lighter weight option for services that would otherwise request membership as SPs, but do not need access to the full set of attributes offered by federation membership. Referring such services to InAcademia, means that Identity Federations are also able to provide an entry-level, low-maintenance alternative to joining the federation, whilst still increasing the number of added-value services available to IdPs as a result.
