The work was initiated as part of the PANData project whose main objective is to provide a high quality data acquisition and analysis infrastructure across most large scientific research facilities across Europe. Its purpose is the implementation of a system to allow scientific users to access resources across the physically distributed repositories at these different facilities. A typical use case would be a user having performed experiments at several facilities who needs to perform the same data analysis on data sets distributed across those facilities. This process involves the use of remote computing resources and software packages; this implies a system whereby a logged user at a local site can be authenticated and authorised in their use of remote facilities. In addition to access to web sites using these single sign on credentials, it is of key importance to enable direct login; the technology of choice is that of project MOONSHOT.
