Synchronization with back-end systems is something Heidelberg needs. We hope to cover do this with the cooperative funding of the AuthN work.

Synchronization is only part of the problem. For .LRN there should also be an API (or a standard way at least) for mapping users to courses, professors to courses, importing course catalogs, etc. Usually universities already have databases with all this info and .LRN needs to be able to communicate with this database.
One of the hardest jobs was integrating GES with the universities database.
