  1. Athens/Shibboleth Integration David Orrell, Technical Architect. Core Middleware Programme Meeting, Loughbrough, 16-17 May 2005.

  2. Overview • Intro: What does project consist of? • Shibboleth-Athens gateway • SAML-Athens gateway • Demonstration • AthensIM • Athens-Shibboleth gateway • Roadmap

  3. Project components • Roadmap set out in Athens ‘Next Generation’ whitepaper, published in September 2004 http://www.athensams.net/shibboleth/athens_ng_scoping_1.0.pdf • Shibboleth-Athens gateway • Shibboleth IdPs -> Athens Service Providers • SAML-Athens gateway • SAML-compliant IdPs -> Athens Service Providers • Athens Identity Manager (AthensIM) • Fully Shibboleth 1.2 compatible IdP • Athens-Shibboleth gateway • Athens Service -> Shibboleth IdPs

  4. Athens Federation Service Provider A Athens usernames (Classic Athens) Organisation A Digital Resource Registration Trust Policies Local usernames (AthensDA) Organisation B SAML gateway Digital Resource Localusernames (SAML/Shibboleth) Service Provider B Organisation C What does this look like? Meta- searching Portal (eg. MyAthens)

  5. Shibboleth to Athens • Goal is to allow Shibboleth IdPs to connect to existing Athens Service Providers • Give Shibboleth IdPs access to a wide range of currently available resources • No change required for Service Providers who have implemented Athens • Athens becomes a Shibboleth Service Provider in its own right

  6. How does it work? • Shibboleth IdP is treated as an entirely devolved identity space from conventional Athens • Shibboleth auth occurs between IdP and Athens gateway • Athens requests attributes for user from Shibboleth IdP • Athens infrastructure behaves as a Shibboleth 1.2 Service Provider • attributes used to establish Athens session • attributes may be passed to Athens DSPs

  7. Resource Athens • WAYF • organisations • access policy Shibboleth protocol What does this look like? Organisation - Shibboleth IdP Athens Agent - usernames - attributes

  8. Attributes • Attributes can be used to assist authorisation • Attributes passed from IdP to Athens are held within the users Athens session • destroyed when session is closed or expired • MAY be passed to DSPs, subject to ARP • Athens provides consistent set of attributes • aids compatibility with Athens resources • eg. organisation identifier, name

  9. Authorisation • Athens resources MAY authorise by: • Athens resource attribute (cf. eduPersonEntitlement) • users own attributes • link to customer database • Gateway supports two methods for allocating Athens resources • default set of resources for organisation (does not require special attributes) • permission set(s) passed to Athens via attributes (maps user to role in Athens) • Desired policy is defined at time of registration

  10. Persistent identifiers • The gateway does not require a persistent identifier to be passed to Athens… • users can remain fully anonymous within Athens • …BUT Service Providers probably do! • If a persistent ID is not passed: • requests from Service Providers for persistent identifiers will fail • read/write requests on a users personal profile will also fail • Persistent identifiers can be passed as an attribute to Athens • eg. eduPersonTargetedID

  11. Federations • Organisations wishing to use gateway will probably already use Athens • have agreed to T&Cs for usage of the Athens service • is current requirement for Athens • Connection to the gateway for production use will require strict compliance with the T&Cs and security policy • membership of the ‘Athens UK Federation’ • organisations will be listed in the Athens WAYF and membership lists • Organisations wishing to evaluate and test the service may join the ‘Athens Touchstone Federation’ • can only gain access to test resources through the gateway • minimal T&Cs • access to own WAYF

  12. Registration • Need to register in order to use gateway: • HS/AA URLs • Handle Assertion signing cert must be securely registered • Choose authorisation policy • Nominate attribute to use as persistent ID • May upload CSR requests to Athens CA • Athens requires that AA server cert is signed by a recognised root CA, currently • Thawte Server CA • Verisign Class 3 CA • GlobalSign Root CA • Athens CA

  13. SAML to Athens gateway • Principle is exactly the same as Shibboleth gateway • Athens supports assertions via SAML Artifact or POST profiles • Attribute, authorisation and registration requirements are exactly the same as with Shibboleth • Proven to work with Novell iChain 2.3 • integration document available • ‘out of the box’ solution • supports both LAA and HDD mode (cf. Athens DA) • Available for trial now

  14. Demonstration • Demo of Shibboleth-Athens demo available at: • http://demo1.athensams.net • Can do demo of iChain-Athens connection on request

  15. Athens Identity Manager (AthensIM) • What is it? • SAML identity provider supporting the Shibboleth profile • Shibboleth 1.2 compatible • 100% Java • GPL licensed • What does it require? • same requirements as Shibboleth software • servlet container + Apache/IIS (optional) • SSO and attribute repository • works with Jetty 4.2.x, Tomcat 4.x/5.x

  16. AthensIM (2) • Why have Eduserv developed it? • Ground-up implementation of SAML IdP based on new architecture • Designed to be clean to configure and easy to support • Can be downloaded with pre-configured servlet container • Full and detailed documentation and integration guide • Provides greater choice for organisations implementing a Shibboleth-compatible IdP • Designed with extensibility in mind, especially addition of configuration and install GUIs

  17. What does AthensIM offer? • Uses a flexible attribute processing chain • Attribute requests pass through chain to retrieve, manipulate and release attributes • Conceptually easy to understand • Very extendable • Very flexible • Full support for multiple Federations • Federations can be separated functionally and conceptually

  18. Extensibility • AthensIM comes with 10 attribute processors • support for LDAP, SQL and XML attribute stores • targeted ID generator • name and values may be mapped based on rules • separate rule-sets can be applied to different Service Providers or users • attributes may be released on a per-provider or per-role basis • …pluggable API so very easy to write your own!

  19. Support • Integration support is available for JISC-funded organisations and projects • AthensIM@eduserv.org.uk • Can be downloaded from • http://www.athensams.net/shibboleth/AthensIM

  20. Athens-Shibboleth Gateway • Reverse of what we’ve previously talked about! • allows Athens users to connect to Shibboleth Service Providers • Athens behaves as a Shibboleth IdP • Attributes delivered via a Shibboleth attribute query rather than via Athens Agent

  21. What does this look like? Resource Organisation Athens • organisations • usernames • access policy - user registry Shib. protocol Shibboleth IdP

  22. How will this work? • Athens will act as an attribute store, SSO, and Shibboleth compatible IdP • Integration of production system will be seemless • Authentication point will detect type of resource user is attempting to access (Shibboleth or Athens) • From users point of view, authentication to Shibboleth resource will not look any different from existing Athens resource

  23. Availability • Service will be made available in two stages • Initial trial service will be based on Shibboleth 1.2 protocol • Will NOT be production service • Will be fully functional and suitable for testing and evaluation • Production service will be available at the same time as the next major release of the Athens Agent (v4.0) • The core Athens service, including Agent will have full SAML support (inc. assertion generation) • Will have Shibboleth compatibility mode • Will have ARP management interfaces • Will be maintained to current Athens service levels • Will run on geographically dispersed infrastructure, redundancy, load balanced

  24. Development roadmap 2005 2005 2006 May June …. Sep …. Q4 Shibboleth- Athens gateway launched Classic Athens to Shibboleth Gateway (trial) SAML-Athens gateway launched (trial) Attribute release policy interfaces for central Athens Agent version 4 release Classic Athens To Shibboleth Gateway launched
