In a single document repository or a library system, the authentication and authorization issues can be handled relatively simply with traditional technologies. However the situation is different in distributed and heterogeneous publication databases. The European DataGrid database access and security design is, among other things, able to take care of the authentication of each user, and the roles of different users across organizational borders. In this paper, we suggest how these Grid tools can be used for accessing distributed publication databases in a controlled and secure way.
