  1. Here Come theFeds Federatedidentitymanagement: theconsumer’sperspective Jens Jensen, STFC On behalf of EUDAT AAI TF EGI CF Manchester April 2013

  2. Background – EUDAT in nuce • EUDAT is building a data e-infrastructure • Support user communities (ESFRI) • CLARIN (linguistics, heterogeneous + long tail) • ENES (climate) • EPOS (Earth obs) • VPH (human physiology) • LifeWatch (biodiversity) • Move data in and out of EUDAT: PRACE, EGI, … • Move data between sites (replication) • Data storage for individual users

  3. Principles: AAI • Authentication • Make use of existing infrastructures • SSO whenever possible • Make use of existing code - pragmatic • Authorisation • Link to community rôles (users can be in more than one community) • Infrastructure • Like the grids, secure with IGTF+commercial

  4. Requirements Scalable (10**7 users) Easy enough to use for “non-technical” users Support long tail researchers (aka homeless) Portal and command line login Mature, robust, performant Standards-based Work with existing community practices (if pos.) Communities manage authorisation policies

  5. Premise • Support existing user communities • CLARIN already using Shib (note the ePTID problem) • ENES already use OpenID (in ESGF) • Provide “authentication services” • Federated identity management • Must work with iRODS for data storage • Must work with GridFTP (and GlobusOnline) for data movement • Must work with Invenio (ORCID)

  6. Plan A and Plan B API Redirect to EUDAT Obtain Access Token Call CA API Plan A Plan B

  7. Evaluations – 2010 Standalone Shib (or SAML) Work with a single community’s portal Use SimpleSAMLPhp EGI or GEMBUS STS Contrail AAI code – see Yvon’s talk Moonshot

  8. Findings • Code satisfying most requirements least mature • Need X.509 – at least internally (GridFTP) • Need good docs for integrators – and effort! • Need to be able to work with betas • Technical collaborations: EGI, EUDAT, Contrail • Supporting multiple communities: • Ends up being kludgy • MyProxy for GO, OAuth2 for ORCID, … • Requirements change regularly • Can spend ∞ time on evaluations
