The CLARIN research infrastructure aims to place language resources and services within easy reach of the humanities researchers. One of the measures to make access easy is to allow these researchers to access them using the credentials issue by their home institutions. However, the technology used for this makes it hard for services to make a delegated call, i.e. a call on behalf of the researcher to other services. In this paper several use cases, e.g. interaction with a researcher’s private workspace or protected resources, show how user delegation would enrich the capabilities of the infrastructure. To enable these use cases various technical solutions have been investigated and some of these have been used in pilot implementations of the use cases. This paper reports on the use cases, the research and the implementation experiences.
