Thanks for your hint, helix. As I said, I had created the metadata field, so the problem was at another place: https://github.com/DSpace/DSpace/blob/dspace-5.6/dspace-api/src/main/java/org/dspace/content/DSpaceObject.java#L1354
Here are some hardcoded fields, like eperson.phone etc. But there is no eperson.ou, that I needed. So this method just returned null and ruined the insert or update. Obviously its not as easy as described in authentication-shibboleth.cfg to use arbitrary fields for eperson.metadata to get from Shibboleth... Thanks, Oliver Am Mittwoch, 4.
