If I try to add an item via REST on DSpace 6 with a user without a WRITE permission to the collection, the submit fails. The user can still use the submission form, but its not possible to add an item via REST.
I get the following information in dspace.log:
2017-11-25 15:28:36,550 ERROR org.dspace.rest.CollectionsResource @ User has not permission to write collection!
This is happening for collections with or without an approval workflow (so a little bit different to the behavior I noticed via SWORD, cf. DS-3766). If I add the WRITE permission to the user, the submission via SWORD works fine, but as far as I understood it, this permission should not be required just to add an item?!
