1 SURFfederatie - eduGAIN Opt-in Metadata Management for a Hub & Spoke Federation

2 SURFnet - We make innovation work1 Content -History of SURFfederatie -Federation models -Functional view -Consequences of hub & spoke -eduGAIN -Future changes

3 Once upon a time… SURFnet - We make innovation work2 Student Chipcard: authentication A-Select: intra-organisational web-SSO DigiD: government eID based on A-Select Federative AAI, A-Select (open source) FIdM service (gateway) in production Elsevier, EBSCO, Google Apps

4 Federation models (communication/login, not metadata) SURFnet - We make innovation work Business VS: SAML 1.x -de-facto -NxN -Shared trust, pt2pt -Education VS/Europa -2xN -Central gateway (CFC) -protocol translation -SURFfederatie = CFC, IDP, SP IDPSP IDPSP IDPSP IDPSP IDPSP IDPSP IDPSP CFC

5 Functional view (Since August 2008) SURFnet - We make innovation work4 Central Federation Components A-Select Cross Shibboleth SAML 2.0 WS-Fed / ADFS SAML 2.0 WS-Fed / ADFS Identity Providers Service Providers SURFfederatie CORE Applications Credential s

6 Metadata & proxying SURFnet - We make innovation work5 IDP 1 IDP 2 IDP 3 SP1SP1 SP1SP1 SP2SP2 SP2SP2 SP3SP3 SP3SP3 WAYF A-1 A-2 A-3 A-1 A-2 A-3 B-1 B-2 B-3 B-1 B-2 B-3 IDP1=B-1 IDP2=B-2 IDP3=B-3 IDP1=B-1 IDP2=B-2 IDP3=B-3 SP1=A-1 {IDP1, IDP2} SP2=A-2 {IDP2, IDP3} SP3=A-3 {all} SP1=A-1 {IDP1, IDP2} SP2=A-2 {IDP2, IDP3} SP3=A-3 {all}

8 hub & spoke pros/cons Pros -1 connection for IDP/SP -Minimal overhead for IDPs -Centralized (technical) management -Specialist SN -Less needed for IDP/SP -Scales well at national level -Extra features easier to do -Web services -Group support SURFnet - We make innovation work7 Cons -Procedures -release consent per SP -Key/cert/metadata changes -Lack of IDP -Double-edged sword… -Scalability European level -Can only support common denominator

14 Future plans -Integrate with SURFconext -Procedural/organisational -Technical (level of integration TBD) -Change of consent model -Opt-in  Opt-out -Addition of User Consent -Web Service support -Needed for (scientific) workflows -Rich client/beyond web SSO/mobile support -Rethink procedures/management SURFnet - We make innovation work13

18 (C) 2011 SURFnet B.V.17 URLs SP die wil meedoen moet SAML doen (want daarvoor zijn we geen proxy zoals normaal) https://wayf.surfnet.nl/federate/surfnet/edug ain 2 IDPS: SN & TERENA 1 SP: TERENA (MDS laat ook zien: TERENA IDP via gateway met URL encoded ipv SAML scoped (zoals WAYF) -> niet iedereen implementeert dat, dus vanwege interop. Doen we het zo. Ook mogelijk om SP specifiek metadata te genereren (per SP uit onze fed) die niet zelf auth lijst willen bijhouden. Bevat SF IDPs + ‘approved’ eduGAIN IDPs

19 (C) 2011 SURFnet B.V.18 Metadata https://aai-viewer.switch.ch/interfederation- test/test/ Wij nu niet saml2int compliant. (behandelen attribs als ‘format unspecified’, moet ‘uri’ zijn volgens spec)
