  1. Shibboleth: Early Experience at OSU Scott Cantor (cantor.2@osu.edu) October 28, 2002

  2. Funding and Interconnections • No OSU funding explicitly supporting work • Tasked with supporting an Ohio Board of Regents grant to develop a platform for competency-based learning (partnership with Apple and WebCT) • Shibboleth a SSO umbrella for deployment of content alongside library resources and WebCT/Blackboard/Angel

  3. Expectations and Motivations • Personal stake in design and development • More comprehensive testing vs. contrived developer testing • Scope work needed to deploy as SSO solution • Demonstrate LMS/Library integration • Extend access to research projects beyond university

  4. General Timeline • Summer ’02: Deploy alpha origin using existing SSO service, assess data situation • Fall ’02: Deploy alpha targets on library’s reverse proxy (ezproxy), OBR development server, LMS testbeds, other local applications (eg. Peoplesoft) • Fall ’02: Participate in I2 pilot with external library vendors

  5. General Timeline • Winter ’03: Migrate to 1.0 code base • Winter ’03: Assess functionality gaps in code, expected time line for enhancements from I2, and scope of work for deployment • Winter ’03: Produce a plan for deployment with funding request attached • Spring ’03: Go / no go • (no go leads to “interesting” decisions on existing SSO system)

  6. Origin Site Alpha DeploymentApproach • Hosting Handle Service behind existing SSO service, so user experience is (mostly) identical between Shibboleth applications and existing applications • Provides clear migration strategy from Handle Service behind SSO to Handle Service as SSO once code supports it

  7. Origin Site Alpha DeploymentIssues • Java made installation simple, but immediately had problems with LDAP (mixture of code issues and local issues), so very limited attributes • Need for cleaner extension mechanisms in AA for custom attributes and caching • OSU’s LDAP service not ready for use, not being actively developed or enhanced at the present time • Comparing scope of work to build out LDAP or use RDBMS with Shibboleth AA

  8. Alpha Target DeploymentsProxying Resources • Main Library rolling out ezproxy as an off-campus access solution • Advised library on ezproxy authentication interface using one time username/passwords • Deployed second proxy with Shibboleth as proof of concept and an OBR project resource • “Real” deployment with proxy would use a routing script to detect on-campus access and bypass proxy, already part of library’s production proxy

  9. Alpha Target DeploymentsInternal Application Development • Deployed Windows port of alpha code to OBR grant development server to support applications being developed • Extended code being reused for project to support EPPN-based authorization

  10. Alpha Target DeploymentsLearning Management Systems • Grant includes assessment of multiple LMS platforms (WebCT, Blackboard, Angel) for compliance with IMS standards and future support for competency-based instruction • WebCT Vista price increase forcing reassessment of LMS platform choices • Angel providing on-site test platform, worked with vendor to support Shibboleth using ISAPI port produced by me for EBSCO (almost working) • WebCT provided a working demo using Shibboleth with external authentication API, not yet used for grant

  11. Alpha Target Deployments800 Pound Gorilla • Parallel, unrelated activity investigating rollout of Peoplesoft self-service components • Some existing ERP-related services (Brio) use campus SSO service already • Common need for improved data to feed Shibboleth and new Peoplesoft applications • Tentative plan to prototype use of Shibboleth as SSO and authorization feed for Peoplesoft, making Shibboleth deployment a component of ERP infrastructure (“follow the money”)

  12. Internet2 Shibboleth PilotProgress • Participating in the formal pilot program, but somewhat under the radar (see funds, none) • Vendors providing direct access with Shibboleth fit seamlessly alongside local resources • OSU access to EBSCO works as of late September • OCLC another possible test • Many databases licensed and accessed through OhioLink consortium, constraining additional choices until they can be persuaded to participate

  13. Internet2 Shibboleth Pilot“Wow, the technology was easy…” • Access to EBSCO worked within minutes of the “try this URL” e-mail from company. • Understanding the contractual picture took days, and is still only imperfectly understood. • We have to understand what Shibboleth means today in order to explore tomorrow. • Does emulating existing policies help with migration, or undermine the business case?

  14. Internet2 Shibboleth PilotNext Steps • Interesting pilots require immediate consideration of how to subset users and communicate this to vendors (affiliation vs. entitlements vs. multiple origin sites) • Need to send knowledge gained back to MACE-Dir to explore directory implications • Need to engage campus resources for wider testing (“I built it, are they coming?”)

  15. Shibboleth at OSUNext Steps • Always viewed as a means to migrate from proprietary Web-ISO system to open standard, with federated features a bonus • Shibboleth 1.0 is not going to be a great Web-ISO, but I believe it is the right design to build on • Document and scope the road from point A to point B • Point A isn’t sustainable, but funds are scarce, so check back in a year (and see if we’re at B or A-1)
