Overall goals and approach of Pilots in AARC
Aims
The Pilots activity aims at facilitating researchers by providing the access management tools and framework to support collaborative research in a distributed environment. To this end, in this activity we demonstrate through (pre-) production services that:
existing AAIs and authentication sources can be leveraged to enable (SSO) access with appropriate level of assurance for any natural person (academia and non-academia) to shared resources offered by different e-Infrastructure providers and communities. (task 1)
authoritative decisions and user/group context can be based on distributed group managers and attribute providers. (task 2)
access to non-web and commercial e-infrastructure services can be enabled. This requires the bridging of SAML (NREN world) and token/certificate based (e-infra world). (task 3)
Approach
The approach consists of deploying existing components as discussed with and identified by JRA1 and to integrate a selection of these components according to a common architecture that has been drafted in JRA1. To this purpose we established a stable pilot environment with solutions to be tried and assessed by stakeholders of the research communities. A more detailed description of the aims and approach of the pilots activity is available here: Specify the work to be undertaken in collaboration with JRA1 and NA3
- Analysis of user- community requirements
- Existing AAI and available technologies for federated access
- The blueprint architecture
Pilots performed
As of March 2017, a large number of pilots have been prepared and lined up as part of the AARC SA1 activity. We assessed the suitability of many different components to handle common issues experienced in R&E. Topics range from handling guest users, managing attributes, to performing token translations. A detailed overview of all components piloted is available here:

Cross infrastructure pilots
This presentation provides a high-level overview and some highlights of the results achieved in this activity:
enable federated access to shared resources of research communities and to enable the integrated use e-infrastructure services, the pilots activity in AARC will run a large number of pilots as a step-up to concrete AAI services. The requirements of research communities and e-infrastructures will drive the design of either missing AAI components or new services. To put this into action the AARC pilots activity consists of 4 tasks:
Table of Contents
Below you find a more detailed description of the activities to be performed for each task
Task1: Pilots with research communities based on use cases provided (lead by GARR and GRNET)
A total of eight use-cases from research communities have been selected to pilot with AAI solutions. A support team will be created to work with the research communities to match the best solutions and architecture with those use cases. Intermediate results will be shared with the relevant communities and feedback will be used to advance the further work.

Task2: Support and pilots for e-infrastructures interoperability and integration (lead by EGI)
This task will focus on piloting AAI components and frameworks to enable transparent interoperability between infrastructures in terms of authentication and authorisation and will build on the state of the art of the AAI services provided by the infrastructures.
This task’s work will be driven by the requirements and use cases of both e-infrastructures and research infrastructures and the results of the JRA1 activity.
| e-Infrastructure | Links | Topics/Focus | Status | ||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| EUDAT-EGI pilot for cross-infrastructure access to resources | The technical integration of the EGI and EUDAT AAIs has started but we recognize that additional effort is needed to harmonise attributes and Level of Assurance (LoA) definitions. The team therefore continues to work on an earlier started joint proposal by AARC, EGI and EUDAT to harmonise the LoA of their identities for consumption by their internal services. | This pilot has been absorbed by the LS AAI pilot | ||||||||
| EUDAT-PRACE pilot for cross-infrastructure access to resources | The high-level goal of this pilot is to achieve AAI interoperability between EUDAT and PRACE and to examine how Unity technology may be used to accomplish this task. The solution consists of two components. The first one is the automatic provisioning of accounts for selected PRACE users who authenticate with x.509 certificates. EUDAT accepts these certificates and PRACE users become registered users in the EUDAT authentication and authorisation service. This gives PRACE users access to non-x.509-based EUDAT services. The second component needs to synchronise these accounts with EUDAT data services using certificate credentials. |

Task3: Piloting advanced use cases, new solutions and approaches based on the outcomes of JRA1 and NA3 (Lead by GRNET)
This task will pilot solutions that complement the eight AAI use cases provided by the selected research communities (piloted within Task 1) and the cross e-infrastructure integration issues addressed by Task 2. As such, the task will investigate advanced AAI scenarios by taking into consideration the results of AARC1 and by building a feedback loop with JRA1 and NA3.
These advanced scenarios include scalable and highly available authorisation schemes in multi-SP environments. In addition, emerging and new technologies (e.g. OpenID Connect for establishing federations, beyond password solutions, integration approaches for multi-protocol cross-sector identity federations) will be assessed and piloted in this task to confirm their feasibility in real-life scenarios.
In addition, this task will deal with cross community use cases. In Q4 2017, Task3 started the Life Sciences & Health pilot for the CORBEL community. This was triggered by a formal request by CORBEL to come up with an overarching AAI infrastructure. Since AAI is not the 'core business' of CORBEL, they prefer having that part sustained by the e-Infrastructures. Therefore, CORBEL wrote a document with their AAI requirements (See: https://goo.gl/zvTQmB) and requested the 3 e-Infrastructures in AARC2 (EGI, EUDAT & GÉANT) to respond with a proposal. It quickly became clear that the best way to approach this respons was to submit a combined proposal, where each e-Infrastructure provides a part of the final solution. A first phase of a pilot has been finalised early February. A recording of the demo is available here: https://geant.app.box.com/v/ls-aai-phase-1-demo. The second phase of the life science pilot commenced in February, results will follow soon.
Task4: Creation of showcases, deployment scenarios and documentation based on successful pilots in AARC2 (Lead by RETI)
The pilots in AARC and AARC2 will produce a lot of experience, documentation and interesting showcases. In collaboration with the NA2 activity, these results will be combined with technical training material and offered as one package to the community.
This material in combination with the relevant sustainability plans, will be fed to the Competence Centre to ensure that a home for the results is found. The results for this SA will be rooted via the for federating communities forum. AARC2 showcases will be used to demonstrate how the proposed AARC blueprint architecture will help simplify the daily work for researchers collaborating in several different communities and using different infrastructures.
Previous results of the pilot activity in the first edition of the AARC project (first edition of AARC 2015-2017) which ended in May 2017, are available here.
