This document is intended for system administrators who would like to register their identity provider for the Elixir Authentication and Authorization Infrastructure (AAI). An AAI delegates the process of registration, authentication and the defining of access rules to different parties: Universities as an example are responsible for registration and authentication of members. Services like e-Learning systems provide the rules for accessing the service. This federated concept shows multiple benefits to services and identity providers such as
Services do not have to provide or implement an authentication and authorization system on its own.
Integration among identity providers such as universities is not needed.
Users do not have to manage multiple accounts and associated passwords (see Single-Sign-On).
The institution responsible for registration and authentication must install a Shibboleth identity provider. Shibboleth is an open source project which is based on the SAML protocol and is designed for federated identity management. As stated on the Shibboleth website it provides support for LDAP, Kerberos and JAAS, and many more.
Step 1: Registration in the DFN¶
The DFN aims to build an authentication federation (DFN AAI) of research institutes and universities and provides a service for aggregating multiple identity providers. This information can later be used by relying services to offer a user to choose his home institutional account. The condition for participating with your Shibboleth installation as an identity provider in the DFN AAI is explained on the DFN registration site
One part of the registration process is also an opt in to the participation in eduGAIN which will be explained in the next section.
Step 2: Opt in for eduGAIN¶
In order to allow interfederational access for researchers, the eduGAIN (EDUcation Global Authentication INfrastructure) project in the context of GEANT was created. From a technical perspective eduGAIN aggregates the data of participating federations and serves the data to relying services. By participating in the DFN you are free to decide whether your identity provider should also be referenced by eduGAIN. Any conditions that must be met by the provider are listed on the DFN eduGAIN page
Step 3: Elixir¶
Elixir unites Europe`s leading life science organisations and offers for services and identity providers an authentication and authorization infrastructure (Elixir-AAI). The infrastructure offers participating services and identity providers additional functionality like group management or a dataset authorization system. The de.NBI Cloud is fully integrated with Elixir AAI. A user can use his university account to access the cloud and any other service provided by de.NBI Cloud. If your identity provider is not listed you can contact Elixir AAI support (firstname.lastname@example.org).
