All Tools

 

The AARC project performed an extensive survey of the AAI tools and technologies in use in the research and education community. The tools are compared in the following tables in terms of their respective feature sets. The features have ben grouped in five distinct use cases, namely: authentication, attribute management, discovery services, credential translation and attribute aggregation.
Each table includes the features used for the comparison in the rows, and one column for every tool or technology. The purpose of this comparison is not to suggest a preferred tool for every use case, since different communities have different requirements and there may not be one-size-fits-all solution.
Tools can support several use cases, therefore tools may  appear in more than one table, based on the use cases they support.

Authentication tools

Authentication technologies are the software and libraries that can be used to allow users to authenticate, and optionally if allowed by the identity provider and requested by the service provider, providing the identity information to another service.

Authorisation

Services can implement authorisation policies based on external information or locally. For distributed infrastructures in particular, it is common for services to use an external policy engine to take authorisation decisions. The purpose for this configuration is to support centralised management of authorisation policies for security reasons, as well as to simplify configuration at service level.

Attribute management tools

The attribute management services store information associated with a user credential, or more user credentials. Identity providers usually provide information, attributes, to describe the user identity, where attribute providers are used by third parties to associate other, community-specific, information with a user.
Typical examples of attributes are membership to a research group, access rights to a service or a dataset orspecific roles within the collaboration.
