Pilot Description

LifeWatch-ERIC is a European Infrastructure Consortium providing e-Science research facilities to scientists seeking to increase our knowledge and deepen our understanding of Biodiversity organisation and Ecosystem functions and services in order to support civil society in addressing key planetary challenges.

LifeWatch-ERIC was established as a European Research Infrastructure Consortium by the European Commission Implementing Decision (EU) 2017/499 of 17 March 2017.

During its ESFRI stage, LifeWatch was composed by different national initiatives working on different services and solutions for the research community. During this new ERIC stage, LifeWatch ERIC requires a solutions to provide access to the different services in a common way, as well as organize the different defined groups and roles. Currently, the different LifeWatch services, Virtual Laboratories and Virtual Research Environment manage their own local users, with some exceptions that allows institutional IDs. The technology behind depends on the services, but they mainly support web-based authentication, with some exceptions using, for example, HPC resources.

This pilot activity aims to identify and enhance an existing AAI solutions to be adopted by LifeWatch ERIC as IdP, integrating already existing institutional or social identities in a federated way.

Pilot goals

 This IdP solution will be used for the following purposes:

  • To give access to restricted LW services. The services may be restricted because of processing power or storage demands.
  • To protect user data and scripts that are stored on the infrastructure (unix home folders etc)
  • To give access to data not yet in the public domain. (data in databases , project moratorium period )
  • To distinguish between users uploading data to the system (RvLab , eLab, data explorer)
  • To give access to openstack configuration interface and computing resources at infrastructure layer.
  • To manage roles/groups and authorize them to access specific services.

Currently, the different user apps manage their own users. The institutional credentials could be federated in the Identity Provider. Also, it should manage the following roles/users:

  • IT administrator who have access at infrastructural level.
  • Developers/Solver who have access to computing/storage resources to develop new Vlabs/VREs.
  • LifeWatch ERIC research users
  • Citizen Science (to have access to concrete applications)

The architecture suggested by AARC based on the blueprint is a promising approach to be adapted to the European framework, in particular for the European Open Science Cloud.



Description

This Pilot, which is based on the AARC BP architecture, deploys a Keycloak instance to work as LifeWatch ERIC IdP, which will b the official user manager solution. It will be deployed on production as a High-Availability service on LifeWatch ERIC ICT resources.
Keycloak satisfy all the expected functionalities, since is is compatible with the most used technologies (SAML, OIDC), it allow IdP federation and allows user group management and attribute mapping. The characteristics provided make Keycloak a promising solution to be adopted instead other available.

During the evaluation phase, different components were checked to decide which one suited the LifeWatch ERIC needs better, including EGI check-in, B2ACCESS, INDIGO IAM, and Keycloak. Finally, the decision was keycloak, an open source solution supported by RedHat and adopted by different communities. The reason for selecting keycloak was the set of features that provides, which are enough for the needs of LifeWatch ERIC as a community:

  • Different ways of user management. Keycloak allows to create a local user in a database or connect with LDAP systems.
  • User federation using the main technologies: OpenID Connect, SAML, Oauth2. It is pre-configured with many different social IDs (Google, Facebook, Github, other keycloak instances). Also eduGAIN.
  • Unlimited federation of IdPs. It is needed for the complex LifeWatch community, with representatives of many institutions.
  • Customizable set of attributes, both in local users as well as federated.
  • Attributes mapping from federated IdPs. It is needed to classify the different expected roles.
  • Group and role management to identify user permissions.
  • Easy to install and maintained. It works with a database that can be distributed.
  • Clustered mode to set up a high-availability environment.

Components

The components are as follows:

ComponentDescriptionWhy did we choose it?Link
KeycloakKeycloak is an open source Identity and Access Management solution aimed at modern applications and services. It makes it easy to secure applications and services with little to no code.

Keycloak fullfil all the required functionalities expected:

  • Compatible: OIDC (priority), SAML (interesting, eduGain).
  • Federation of 1-N Institutions. Citizen Scientists (Social IDs).
  • Roles Management. Role mapping (e.g. Google users to Citizen Scientist).
  • Identity linking (optional).
  • Group Management. Some groups are allowed to do…
  • Distributed, clustered. High availability. NATIVE

FEUDAL

Federated User Credential Deployment Portal.

One possibility to link between the IdP (Keycloak) and a "non-compatible" service.https://hdf-portal.data.kit.edu/
WaTTS

WaTTS allows using any legacy service with federated identities, such as eduGain or google.

For this, WaTTS accepts federated identities (via OpenID Connect) and uses a plugin scheme to generate credentials for your service. This allows you to provide services that do not normally support federated identities to federated users.

Architecture



Pilot Vs AARC BP

Use Cases

Access to Rshiny
1.

Access RShiny research service to analyze/calculate thermoclines in water columns.

 

 

Afbeeldingsresultaat voor browser icon

2.

The User is redirected to LifeWatch IdP

3.

You can select among the list of federated institutions belonging LifeWatch. For example, IFCA SSO will redirect you to the IFCA IdP

4.

Overview of attributes being shared (to authenticate and perhaps authorize)...... 

5b.

The user is successfuly redirected to Rshiny app

   

Use Case 2 - User Role Mapping (Researcher Vs. Citizen Scientist)


Access to Rshiny (for the moment)
1.

LifeWatch ERIC IdP needs to federate different institutions and different social ids to distinguish between different types of users (Researchers, citizen scientists...).

 

 

2.

Keycloak allows mapping to defined roles depending on the identity provider used for accessing.

4.

It can be configures to propagate that information as an attribute for a service.

5.

So the service can get that info and decide if the user has or not access rights.
