Using Dspace 5.9.
I created a collection with default authorization and uploaded 100 items with the default authorization.
But then, the client decided to allow the READ policy only and remove the DEFAULT_BITSTREAM_READ policy for Anonymous group.
Reading across the forum, I learnt that the easiest way would be to create another collection with this required authorization and move the 100 items from old to this newly created collection, selecting "Inherit policies of the destination collection".
I did, but the older DEFAULT_BITSTREAM_READ policy for Anonymous group did not get overridden. The items can be still opened as Anonymous.
Help please.
