One is a social2SAML gateway, and Paul Caskey of UT System is standing up a trial gateway. The other is leveraging functionality new to the Shib SP in version 2.5 (release candidate now available) that allows authN plugins that would facilitate adding social IdPs to an SPs supported modes of authentication.

As of this moment, Chris Hubing at the University of Pennsylvania and Keith Hazelton (UW-Madison and Project Bamboo) are committed to trials of such Shib SP-based solutions. Chris has an implementation configured and working and intends to document his approach once he irons out a couple issues.</div></div><div><br></div><div> Looking forward to hearing from interested parties, --Keith Hazelton</div></body></html>
