Helmholtz Portfolio Theme Large-Scale Data Management and Analysis (LSDMA)

The Helmholtz Association funded the "Large-Scale Data Management and Analysis" portfolio theme from 2012-2016. Four Helmholtz centres, six universities and another research institution in Germany joined to enable data-intensive science by optimising data life cycles in selected scientific communities. In our Data Life cycle Labs, data experts performed joint R&D together with scientific communities. The Data Services Integration Team focused on generic solutions applied by several communities

Combining the X.509 and the SAML Federated Identity Management Systems

Every distributed computing infrastructure requires authentication and authorisation infrastructures (AAI) to manage access to resources and content. Several of such so called AAI systems are in use within different groups of users. In the Large Scale Data Management and Analysis project we aim to support and bring together many user communities. We therefore need to harmonise the currently used AAI systems. The approach described is to translate between different authentication systems. We furthermore try to maintain the same trust level wherever possible, and to harmonise authorisation across the involved systems
