Promoting Interfederation in the InCommon Technical Advisory Committee

"The InCommon Technical Advisory Committee aims to facilitate interfederation between the InCommon Federation and other SAML federations. International collaborations and successful pilot projects demonstrate the benefits of interoperability. Next steps include enhancing metadata exchange, supporting hierarchical and bilateral interfederation, joining eduGAIN, and providing a production interfederation metadata aggregate. Participation information is available on the InCommon website."

  1. Interfederation subgroup of InCommon Technical Advisory Committee (TAC) spaces.internet2.edu/display/incinterfed

  2. Mission • Promote and pursue interfederation between the InCommon Federation and other SAML federations via a community-based process • Both policy and technical aspects are in scope

  3. Relationships • refeds.org – int’l forum for interfederation discussions • edugain.org – interfederation service • other federations, including: – UK Access Management Federation (Ian Young) • ukfederation.org.uk/content/Documents/InterfederationTrialFAQ – Canadian Access Federation (Chris Phillips) – University of Texas System Federation (Paul Caskey) – K-12 enabled by regional networks (Mark Scheible) • www.thequilt.net/index.php/events/246-2013-quilt-incommon

  4. Deliverables (June 2013) • Use Cases spaces.internet2.edu/x/EQAwAg • Plans for InCommon and UK Interfederation spaces.internet2.edu/x/tIA_Ag • Lessons Learned spaces.internet2.edu/x/QwBOAg • Report to Technical Advisory Committee (TAC) • Links at spaces.internet2.edu/display/incinterfed

  5. Use Cases • International collaborations – (LIGO, NIH, Internet2, TERENA, Shibboleth) • Online university course with int’l enrollment • University published journal with int’l subscriptions • Campus federations • University system federations • K-12 • Community colleges • State agencies • Federated wireless (eduroam)

  6. Interop Across Federations • Entity-to-entity metadata exchange – IdPs and SPs exchange metadata directly with each other. – Examples: 1) Google Apps and 2) LIGO SPs + KAGRA IdP in Japan • Entity joining multiple federations – IdP or SP joins multiple federations to enable interoperability. – Example: LIGO (an InCommon member) also joining Italian Identity Federation (IDEM) • Bilateral interfederation – Two federations enable interop across their combined membership. – Examples: UK with Edugate (Ireland) and (possibly) InCommon • Multilateral interfederation – Multiple federations join a common technical infrastructure and/or policy framework. – Examples: eduGAIN and Kalmar Union • Hierarchical federation – Examples: 1) U Texas System + InCommon and 2) Regionals (The Quilt) + InCommon

  7. Successful Interfederation Pilot LIGO users at Cardiff University (UK) logged in to LIGO wiki (US/InCommon)! Thanks to Steven for metadata aggregate Ian for UK federation coordination Scott for LIGO SP configuration Rhys for Cardiff IdP configuration

  8. Potential InCommon Next Steps • Add PublicationInfo and RegistrationInfo to metadata – Helps with metadata aggregation across federations • Support hierarchical federation – Automated import of external federation metadata • Support bilateral federation – Build on pilot effort with UK federation • Join eduGAIN – For multilateral federation • Provide a production interfederation metadata aggregate – Stable source of external entity metadata • Support additional entity tags in metadata – SP privacy policy, IdP discoverability, etc.

  9. To participate, visit: spaces.internet2.edu/display/incinterfed • Weekly calls Tuesday noon Central Time • Join the interfed@incommon.org email list All are welcome!
