We would like to login with SAML through eduGAIN

There is a "new" interfederated login with SAML through eduGAIN

Blekinge Institute of Technology (BTH) is a member of the Swedish Academic Identity Federation – Swamid.
There are similar solutions for universities around the world.
Swamid is a member of the Interfederation eduGAIN (https://edugain.org/).

Our IdP is published through the Swamid Metadata and eduGAIN interfederated Metadata.
The metadata for the IdP (supplied through Swamid/eduGAIN) is stripped, so it only contains the necessary information for the federated authentication.
We prefer that all federated authentication and Metadata exchange are handled through the eduGAIN interfederation, instead of creating/setting up a direct federated trust between our IdP and external SPs.

This authentication can be used as a replacement for the proxy and will be much easier to work with for users and librarians.
Most publishers have already support for this :)
