  1. AAI @ TERENA EUROCamp 2010 DyonisiusVisser visser@terena.rg www.terena.org

  2. Where it all started • REFEDS Wiki • Dog food • MediaWiki+ SimpleSAMLphpAuth • One SP • Accumulated > 20 IdPs <lastname@terena.org>

  3. Next SP comes along • TACAR  • Will need to contact several IdPsagain to exchange metadata  • 3rd SP • 4th SP etc etc

  4. Too many IdP-SP combinations • Difficult to manage:

  5. New approach: cheating • Create one SP to connect all our IdPs to • “Hide” all our REAL SPs behind that • External IdPs only do business with a single TERENA SP • We get to do fancy stuff at our magic SP

  6. What could be the “?” • Attribute injection • authproc: SmartAttr.php

  7. SmartAttr.php • Generate globally unique identifier for ALL possible users • Pick first available attribute name+value from: • eduPersonTargetedID • eduPersonPRincipalName • openid • sha1(salt.serialize(attributes)) • Append @$IdP • Results:

  8. SmartIDexa,mples: • urn:mace:dir:attribute-def:eduPersonTargetedID:c4bcbe7ca8eac074565291fd5524caa88f3115c8@terena.org@https://login.terena.org/idp/saml2/idp/metadata.php • urn:mace:dir:attribute-def:eduPersonPrincipalName:horvath@terena.org@https://login.terena.org/idp/saml2/idp/metadata.php • openid:https://www.google.com/accounts/o8/id?id=AItOawk1wEwIIRLSKf6kWb_1Rb0X00psc3lPqWU@https://login.terena.org/bridge/saml2/idp/metadata.php

  9. More attributes • Fullname: Stolen from Olav  • Organisation:first available from: • organizationName • Uppercase version of schacHomeOrganization, without TLD • Uppercase version of email domain without TLD • Uppercase version of eduPersonPrincipalName domain without TLD • String ‘MY_ORG’ • Country, fname, lname, email, etc

  10. Group membership • To be implemented…..

  11. Concepts • We will have homeless users -> guest accounts • Everyone can login to any service • “logged-in” does not mean anything (well….) • https://tnc2010.omega.terena.org • One page to manage all your data (‘profile’ page) • Similar to Switch.ch javascript sidebar • To be implemented

  12. Issues encountered • Changing your SP metadata at remote parties takes a long time  non-technical, so think twice • Non-federated users – don’t run ourselves • Too may guest options now!!! • Provisioning before users log in -> not possible • Globally persistent ID
