Title: Cant, Claptrap and Collectivist Shibboleths the ShibboLEAP Project


1
Cant, Claptrap and Collectivist
Shibboleth(s)(the ShibboLEAP Project)
  • John PaschoudLSE Library Projects Team
  • London School of Economics Political Science,
    UK
  • Project Manager, ShibboLEAP

2
What is (a) shibboleth? (Biblical)
  • A word which was made the criterion by which to
    distinguish the Ephraimites from the Gileadites.
    The Ephraimites, not being able to pronounce
    sh, called the word sibboleth. See --Judges
    xii.
  • Hence, the criterion, test, or watchword of a
    party a party cry or pet phrase.
  • Webster's Revised Unabridged Dictionary (1913)

Judges, ch12, v5-6 (New American Standard) The
Gileadites captured the fords of the Jordan
opposite Ephraim. And it happened when any of
the fugitives of Ephraim said, "Let me cross
over," the men of Gilead would say to him, "Are
you an Ephraimite?" If he said, "No," then they
would say to him, "Say now, 'Shibboleth.' " But
he said, "Sibboleth," for he could not pronounce
it correctly. Then they seized him and slew him
at the fords of the Jordan. Thus there fell at
that time 42,000 of Ephraim.

What are shibboleths? (Political)
The greatest needs of the Collectivist movement
in England appear to me The diffusion of
economic and political knowledge of a real kind -
as opposed to Collectivist shibboleths, and the
cant and claptrap of political campaigning. Sidne
y Webb memorandum to LSE Trustees meeting on
8th Feb 1894 LSE Archives/1/1

Hmmm.
  • Actually, doing Shibboleth collectively might be
    quite a good way to make it easier, for a lot of
    people / institutions
  • Where can we find a bunch of them, with something
    in common?
  • and wed have to think of some excuse for
    something to access, because there arent many
    Shibbolized publisher resources yet, and the
    Shib-Athens Gateway doesnt work yet
  • What about Institutional Repositories (Shibbo
    LEAP)?
  • Dont be silly! You cant do Access Management
    with them! Theyre meant to be open! (Didnt
    you read all that OAI stuff from Stevan Harnad I
    sent you?)
  • Well, maybe we can get the money before anyone at
    JISC figures that out.

JISC Core Middleware Infrastructure Programme
  • UK Govt Spending Review grant (3.4 million
    across two years) to achieve specific aim of
    working federated access management
    infrastructure
  • Focused activities
  • Shibbolising of JISC resources held at MIMAS and
    EDINA (national data centres)
  • Funding for a support service MATU at Eduserv
  • Early Adopter funding to help institutions
    implement required technologies (two calls, 26
    institutions)
  • Regional Early Adopters to explore e-Learning
    collaborations with federated access
  • Funding for initial development of full federated
    service UKERNA
  • Communications and outreach programme e.g.
    letters sent to all HE institutions
  • Completes July 2006
  • Full federated access management services to be
    in place by September 2006

The ShibboLEAP Project
  • April 05 April 06 approx 250K JISC funding as
    Early Adopters of Shibboleth
  • (no acronym just a badly-chosen email
    subject-line that stuck)
  • 6 other University of London Colleges, assisted
    by LSE with technical expertise project
    management
  • Already associated because they were
    participating in the (national) SHERPA pilot of
    Eprints as institutional repository
  • (LEAP London Eprints Access Project)
  • The SHERPA-LEAP consortium
  • Birkbeck College
  • Imperial College
  • Kings College London
  • London School of Economics Political Science
  • Royal Holloway College
  • School of Oriental African Studies
  • University College London

ShibboLEAP partners
  • a diverse collection of institutions - all on
    our doorstep!
  • Some have lots of undergraduates studying diverse
    subjects
  • Some are focused on small range of subjects
  • Some concentrate on postgraduate studies and
    research
  • Some focus on continuing education
  • All have well-regarded research programmes
  • Most already had LDAP directories of users
  • Some used project to replace existing directories
  • Most common software Active Directory
  • None had eduPerson object class installed
  • Size and formality of IT department varied widely
    (5 - 35 network/internet techies)
  • but quite a useful lot to get the UK Shibboleth
    ball rolling!
  • Total population of LSE 10,000
  • Total population of consortium 150,000
  • (Total Shibboleth-enabled population of
    Switzerland, at that time 140,000)

13
Project objectives
  • Enable full Shib IdP for all users at each of the
    7 partners
  • Using their existing directory other
    infrastructure services where possible
  • whatever they are (THE TRICKY BIT!)

Project objectives
  • Enable full Shib IdP for all users at each of the
    7 partners
  • Using their existing directory other
    infrastructure services where possible
  • whatever they are (THE TRICKY BIT!)
  • Access via Shibboleth to external resources which
    is
  • secure limited to those people that are truly
    entitled to access the resource
  • accountable through Shibboleth log files and
    institutional systems abusers can be tracked and
    dealt with
  • up-to-date leavers are quickly and accurately
    prevented from further access while newcomers are
    granted access straight away
  • Enable Eprints software as a Shib SP
  • As fully as possible within the project budget
    timescale
  • Contributed back to OSS development of Eprints
  • Produce a documented production process for Shib
    implementation by others
  • and maybe also a model for other peer-support
    implementations?

16
Role-based access in an open archive
Institutional Repository
  • (Open as in Open Archives Initiative - based
    on Eprints or another harvestable repository
    server like DSpace, etc)(We also have a
    Shibbolized DSpace)
  • Who is permitted to do what
  • deposit papers (your own academics)
  • add edit metadata (library staff who know what
    metadata is)
  • authorise publication (1 or 2 administrators)
  • Some (at least) of these roles should be
    derivable from existing directory attributes
  • ePSA staff_at_lse.ac.uk
  • ePSA staff_at_lse.ac.uk AND ou library
  • ePE EprintsAdmin

17
Shibbolizing Eprints
  • AuthN (easy!)
  • to eliminate yet-another-password for users
  • User identity/privacy is not an issue
  • eduPersonPrincipalName (e.g. paschoud_at_lse.ac.uk)
    can be used to link to personal account within
    Eprints
  • AuthZ
  • How deeply embedded in code is the permissions
    structure?
  • How much of this can we (do we want to) represent
    as generic attributes in an institutional
    Enterprise Directory? (probably LibStaff,
    AcStaff as scoped affiliations)
  • so some will (probably) remain internal (but
    could be represented as eduPersonEntitlements)
  • Anyway, we must do this as install-time options,
    because different institutions will make
    different choices

19
Project management
  • Herding cats???
  • Regular Library and IT service staff involved at
    each site
  • Two posts funded part-time by project
  • High-level buy-in (service directors)
  • Some cooperation Some competition
  • Focussed Project Management Board governance
  • Defined tasks for each planned meeting
    throughout project
  • Easy-to-measure (although bogus) primary
    objective
  • Shib access to Eprints repository works
  • so everything else will!
  • Few critical inter-dependencies
  • So low risk of failure

20
Key milestones
21
Lessons learned Who Needs to be Involved?
  • Network account techies
  • Athens administrator (in UK)
  • Directory admin techies
  • Firewall and security techies
  • Library IT staff and librarians who know your
    electronic resources
  • Managers for the above!

22
Lessons learned Where are you Starting From?
  • What is your institutional directory?
  • Who in the institution owns it (and how can you
    be their friend)?
  • How is it updated?
  • How do you arrange to change it?
  • Or should you be considering a new directory
    solution?
  • Does it contain all the information likely to be
    needed for resources protected with Shibboleth?
  • How do you currently handle user account
    management?
  • Are user credentials secure enough for
    single-sign-on use outside the institution?
  • Do you already use a Web ISO solution such as
    pubcookie?
  • Where will you install the Shibboleth Identity
    Provider?
  • On what type of machine?
  • How are you planning to connect it to the
    institutional directory?

Case Study 1 Small Research Institute
  • Approach
  • Used in-house cookie authentication system as
    backend, and Novell eDirectory as institutional
    directory
  • Updates performed on live directory server with
    no problems
  • Difficulties encountered
  • Trivial configuration errors simple to fix (when
    found...)
  • Every thing is nice and informal, changes to
    the directory got done quickly on the live
    service, kit installed and setup without anyone
    looking over my shoulder, no need for meetings,
    committees etc.
  • But...
  • From a professional systems point of view some
    testing on a dev system would have been a good
    idea. Things turned out OK though so shouldn't
    complain.

25
Case Study 2 Large Undergraduate College
  • Approach
  • Used mod_auth_ldap for authentication, IPlanet
    LDAP server as institutional directory (but
    separate test server with limited number of
    accounts used for initial IdP installation)
  • Institutional wildcard certificate used to
    certify Shib communications
  • Difficulties encountered
  • Difficulty installing IdP resolved by moving
    from RH Fedora to RHE3
  • Large team makes it easy to find relevant
    experience for solving installation problems
  • But...
  • Bureaucracy makes life harder

26
From Project to Production
  • Most institutions set up first Shib IdP in
    project context
  • Limited (but rapidly growing) number of resources
    available via Shibboleth
  • (the Shib-to-Athens Gateway is particularly
    useful for this)
  • but we dont want it to inhibit proper
    adoption of Shib by vendors!
  • Few will want to take a big bang approach and
    replace all existing, working-well-enough
    authentication regimes with Shibboleth at one go
  • Prioritise resources need to balance usefulness
    against ease of changeover
  • May require contacting publishers, which can help
    persuade them to implement Shib if not doing it
    yet
  • Consider new installation of IdP for production
  • Ideal for teaching mainstream IT staff to
    understand Shib be able to support it
  • See Shib for Sysadmins package

Where are THEY now?
  • Most of the partners in ShibboLEAP are now
    working together on
  • The Identity Project
  • - a comprehensive audit of Identity Management
    across UK FHE, using partners to create and
    test a re-usable model for detailed institutional
    audits of Identity Management
  • (the bits that the IT Director knows about and
    what s/he doesnt know about!)
  • Only two of the original partners (LSE and UCL)
    are currently registered as production Shibboleth
    IdPs in the SDSS Federation
  • (so maybe this was slightly too early adoption,
    for some, in relation to the overall JISC
    transition timetable?)
