Presentation Transcript

  1. What is REFEDS Interested In? Nicole Harris UK Access Management Focus, JISC Advance @nicoleharris Slides: http://www.slideshare.net/nicolevharris

  2. Me • UK Access Management Focus; • Advisor to UK federation; • REFEDS Coordinator; • PEER Project Manager; • Shibboleth Consortium Manager; • Generally opinionated about access and identity.

  3. What does the R&E Federation space look like?

  4. R&E Federations Status (1)

  5. R&E Federations Status (2) • 27 Federations plus 2 confederations. • 4753 entities within those federations. • 1815 Identity Providers. • 2755 Service Providers. • Plus several ‘others’ (don’t worry about it). (November 2011)

  6. Top resources? • In 14 federations: • Czech Medical Atlas and Microsoft Dreamspark. • In 12: • Web of Knowledge, Scopus, ScienceDirect. • In 11: • IEEE, EBSCO. • In 10: • Springer, OVID.

  7. So it’s all working, right?

  8. For SPs, Federation Sucks I know because I wrote a paper on it!

  9. Barriers • Multiple registry of entity data. • Multiple legal documents. • One-off clauses. • Interpretation of data protection. • Sponsorship letters. • Fees. • Technical Barriers. https://refeds.terena.org/index.php/Barriers_for_Service_Providers

  10. Registering Entity Data • Federations are just big metadata (xml) files. • Entity = your chunk of that data. • It goes a bit like this:

  11. How does it work? Federation A Federation B Federation C You

  12. What we need is a place where this can be centrally registered and then called on by federations…

  13. PEER http://beta.terena-peer.yaco.es/

  14. Legal Contracts

  15. Wouldn’t it be great if these were standardised and simplified?

  16. REFEDs Policy Review • Painstakingly taking apart every clause in every federation policy. • Mapping these to generic content ‘blocks’ and ‘elements’ within each block. • Making recommendations about structure and unnecessary language. • NOT a legal review.

  17. Isn’t there an easier way?

  18. Full Interfederation • The ability of federations to exchange metadata about their entities. • Normally an additional legal agreement between the 2 federations. • Full technical and policy integration. • Bi-lateral (UK and Edugate) or via groups (eduGain and Kalmar2).

  19. eduGain (1) www.edugain.org

  20. eduGain (2) – Drawbacks • At least one of the federations you are a member of needs to have signed up for eduGain. • Opt-in: you have to ask to be included in an aggregate. • Not always clear which entities are interfederated – are your customers there?

  21. eduGain (3) Benefits • Only have to have a relationship with 1 federation. • Technically, as an SP, you can chose with federation that is.

  22. A quick note on Barriers to Users

  23. Login Interfaces Suck I know this because I’ve tried to use them

  24. How Bad?

  25. New UK federation WAYF

  26. Foodle and DiscoJuice

  27. MDUI • Currently being used by DiscoJuice and Shibboleth Embedded Discovery Service / Central Discovery Service. • OASIS Standard for IdP Discovery: • http://docs.oasis-open.org/security/saml/Post2.0/sstc-saml-idp-discovery.pdf.
