SWITCHaai: 1’000 services registered

Last week, the number of services registered in the SWITCHaai federation crossed the 1’000 line for the first time.

When the Università della Svizzera italiana, Damiano Bianchi (Servizio informatico TI-EDU) registered the ‘USI Library service’ (the 21st service of USI), this new service became the 1’000th SP available in the SWITCHaai federation.

It’s the first time in the history of SWITCHaai that we have reached this number of registered SPs. Due to old services getting deleted and new ones registered, the actual number of services slightly fluctuates. However, in general it has been steadily increasing since the production SWITCHaai service was launched 12 years ago in autumn 2005 (see the graph in the lower right corner in the growth picture below).

The steady growth of the SWITCHaai Federation

The SWITCHaai federation serves the higher education community in Switzerland and Liechtenstein: More than 99% of all students, staff members and researchers at universities, universities of applied sciences and teacher education universities have a SWITCHaai-enabled user account. With their account, they can access a wide variety of services. Users as well as service administrators enjoy the benefit of no service specific user accounts required!

In addition, more than 100’000 further users from about 20 university related institutions have user accounts that provide them also access via SWITCHaai.

SWITCH and the SWITCHaai federation participate in the development and use of eduGAIN, the GÉANT interfederation service that interconnects more than 40 federations world-wide.


Consultation on draft of federal E-ID law

At its meeting on 22 February 2017, the Swiss Federal Council opened a consultation on legislation on electronic identification (E-ID law, see announcements: DE, FR, IT). The consultation ended 29 May 2017.

SWITCH participated in this consultation and confirms the importance of a well-functioning and generally accepted E-ID. The identity service SWITCH edu-ID/SWITCHaai could potentially benefit from such an E-ID legislation: either to start offering an E-ID function itself, or by consuming E-ID services. Such use cases – from SWITCH and from other parties – may become important drivers for the spread of E-ID beyond pure e-government applications and for the emergence of an general-purpose E-ID ecosystem.

After evaluating the proposed delivery model in the draft E-ID-law, SWITCH proposes its revision. To ensure swift implementation and to reduce risks and complexity, SWITCH urges that the proposed market model be abandoned in favour of an implementation by the Swiss Confederation itself or by mandating it to a third party.

If the market model is to be pursued nevertheless, SWITCH proposes the use of a multi-stakeholder expert group to resolve the many open questions arising from the draft. If this group can not achieve its objectives, the market model is to be abandoned once and for all in favour of the proposed government-driven implementation model for an E-ID.

Real SSO feeling through the SPNEGO/Kerberos Login Flow for the Shibboleth Identity Provider v3

Windows users can now extend their SSO feeling to the SWITCHaai login page, provided their client is a member of a Windows domain. They no longer need to re-enter their username and password they’ve already entered to log in to the Windows desktop. Actually, Kerberos enabled non-Windows clients like Linux or Mac could profit of such enhanced SSO, too.

The Shibboleth Identity Provider (IdP) achieves this through SPNEGO-based Kerberos authentication (i.e. password-less web authentication via Kerberos). While version 2 of the Shibboleth IdP supported this through an extension, the Shibboleth IdP version 3 provides built-in support through the SPNEGO/Kerberos Login Flow authentication mechanism.

The SPNEGO/Kerberos Login Flow module was developed in co-operation by SWITCH and the Fachhochschule Nordwestschweiz (FHNW). As the FHNW already developed the extension for the IdP v2, they brought their existing experience into the project to re-implement the same functionality for IdP v3. Eventually, the SPNEGO/Kerberos Login Flow got an integral part of the Shibboleth Identity Provider version 3.2.0 in November 2015 and has been available since then.

The SPNEGO/Kerberos Login Flow has proven to run successfully on the IdPs of the Fachhochschule Nordwestschweiz and the Pädagogische Hochschule Bern, since these IdPs were migrated to IdP v3.

To use the SPNEGO-based authentication, the following prerequisites must be fulfilled:

  • A Kerberos infrastructure must be available (e. g. a Windows domain).
  • The IdP server must be registered as a Kerberos service at the Kerberos Key Distribution Center (KDC).
  • Kerberos client software must be installed on the IdP server.
  • The Shibboleth Identity Provider software must be configured accordingly.
  • The web browsers on the clients require specific configuration to use this authentication method.

Organisations being interested in using the SPNEGO-based authentication on their own IdP can find comprehensive documentation in the Shibboleth Wiki: SPNEGO/Kerberos Login Flow

SPNEGO-based authentication is also offered as an option to the Identity Provider Hosting service provided by SWITCH.


SWITCHaai Transition to Shibboleth Identity Provider v3 is 80% complete

Back in May 2015, the Shibboleth Consortium announced July 31st 2016 as end-of-life date for the IdPv2 code base. A redesigned IdPv3.1.1 is available since March 2015. One month later, SWITCH announced the initial version of the SWITCHaai specific IdPv3 installation guide. In June and September 2015, SWITCH offered well-attended IdP training courses [4] on how to configure IdPv3. Since then, the number of IdPv3 installations has gradually increased to the 80% level it reached just at the beginning of the autumn semester 2016.

The vast majority of the IdP administrators have installed, configured, tested and finally integrated the new version into their production environment. A big thank you to all of them that they gave their time to upgrade. Many administrators provided us valuable feedback on the IdP installation guide so that we could continuously improve it over time.
Several organizations decided to adopt the IdP Hosting service SWITCH offers instead of upgrading their own local installation. Today, SWITCH runs 17 production IdPs on our IdP hosting platform, including the ones for Swiss edu-ID, the Virtual Home Organization (VHO) and the IdP for the SWITCH staff members.

From about half of the remaining eleven IdPv2 instances we know that they will migrate to IdPv3 in the next few weeks. So hopefully by the end of 2016 almost everyone will have completed the transition.

The US InCommon Federation from time to time analyses the metadata of the eduGAIN interfederation service and publishes an interesting statistic on how many of the interfederation enabled IdPs are based on the Shibboleth open source software and run on IdPv3 or still on IdPv2. These numbers show that the percentage of IdPv3 in SWITCHaai is pretty high compared with most other federations listed.


Trust in federated AAI: with a particular attention to SWITCHaai

SWITCHaai has a long and successful history in enabling access to hundreds of mainly academic web resources by reusing the authentication mechanisms at the heart of participating organisations.

When joining the SWITCHaai team a couple of years ago, I noticed two things about trust: a) it was just there, and b) no one talked about it. “Trust is established when no one talks about it anymore” someone said. It made me wonder how such a unique construction could be there and just work. There must have been many detailed questions that had to be resolved to get to that point! My curiosity was piqued, so, I started delving into this fascinating topic. How come all of these many service providers, identity providers, end users, organisations and federation partners, commercial or not, just do what the others would expect from them and don’t break trust?

Let’s start with an overview of the roles within an identity federation and their particular expectations towards each other and the federation as a whole. Continue reading
