  1. JISC Metaleth Project Athens, Shibboleth and the University of Bristol 29th January 2007

  2. Outline • What changes to access management are JISC proposing? • What is Shibboleth? • What will these changes mean • For end-users? • For UoB staff? • What are the timescales? • What are the UoB plans?

  3. What is happening? • JISC is aiming to improve theway in which users access resources throughout the UK educational sector • Goal: to allow users to access internal and external resources seamlessly using a single, institutionally controlled identity • Reduce substantially (if not eliminate altogether) current problems in which users are required to maintain multiple passwords for multiple resources in multiple domains

  4. What is happening? (2) • JISC support for Athens will cease • Athens will be available as a paid-for service • New JISC strategy based on Shibboleth technology, a new standards-based approach in this area

  5. Why the move from Athens? • Relies on separate credentials • Forgotten or written down (a security issue) • Shibboleth uses local credentials • Demand for more sophisticated systems for enabling access to materials and resources • Shibboleth’s flexible design provides a good basis for meeting these demands.

  6. What is Shibboleth? • Federated access management framework • Federation of Identity Providers (IdPs) and Service Providers (SPs) • No central identity service • SPs talk to user’s IdP • Authorisation decisions based on IdP-provided information • Federation provides trust fabric • Allows SPs and IdPs to trust each other

  7. What is Shibboleth? (2) • Acknowledgement: • Taken from SWITCH AAI

  8. What is Shibboleth? (3) • For web services only • Integrated with localauthentication • Single Sign OnCAS in UoB case • Location independent • Won’t necessarily provide UoB IP address to those services that use IP addresses to make authorisation decisions

  9. What changes will there be for end-users? • Single Sign On extended • To UoB resources protected by CAS SSO • To third-party resources protected by Athens or Shibboleth • Users will have to negotiate new WAYF step • Techniques to reduce the impact of this

  10. What changes will there be for UoB staff? • No more separate Athens identity management • Users will login to UoB SSO when visiting external protected resources • In time, no separate account management for non-UoB users • e.g. external Blackboard users

  11. What changes will there be for UoB staff? (2) • UoB will have to run (or outsource) a Shibboleth IdP • Linked to LDAP and CAS SSO • One for the techies • Attribute exchange with resource providers will have to be managed • Again, one for the techies

  12. What support is there? • JISC-provided UK AccessManagement Federation forEducation and Research • UoB experience from JISC-funded pilot project • Metaleth (Metalib + Shibboleth) • A Shibboleth to Athens gateway • Provided by Eduserv

  13. What is the time frame? • JISC asking institutions to recognise this change within their IT strategies for the next two years • Athens contract with JISC renewed until July 2008 • Will run in parallel to the UK access management federation and the Athens/Shibboleth gateway • From July 2008, JISC will support access management through the UK access management federation • Athens will become a paid-for service

  14. What are the next steps we need to take? • UoB currently evaluating alternate approaches • Run the Shibboleth infrastructure ourselves • Identity provision, Attribute Authority • Outsource to Eduserv

  15. What are the next steps we need to take? (2) • Project starts in April • Goal: replace Athens at UoB for the Autumn • Tasks: • A production Shibboleth IdP • Transfer of current Athens-protected resources • Shibboleth directly or via Athens/Shibboleth gateway • Policy decisions to be taken regarding attribute release and privacy • Managing the change-over for end-users • Documentation, awareness raising
