Abstract

The combination of services that provide personal information in technologies such as educational mashups brings some issues in the management of users' identity and authorisation. This article presents a scenario based on the fact that an IMS LD server requires information relevant to each learner, and this information is provided by external services. This scenario allows to describe the problems of user correspondence, authenticated data retrieval, and remote account creation; a solution using technologies currently available is provided for each, as well as recommendations to take into account in similar scenarios.
