You can do bulk updates to item and bitstream policies by going to Administer 
-> Authorization -> Advanced / Item Wildcard Policy Admin Tool.  You can get 
more help on the online help on that page. You might want to backup your 
database before bulk updating things.

Are you uploading new bitstreams after you change DEFAULT_BITSTREAM_READ?  This 
policy only affects the new permissions set on bitstreams when they are 
uploaded.

Subject: [Dspace-tech] restricting users to a specific collection

Hello everybody,

I am using dspace 1.6.2 on windows server 2008.
i am suffering with authorization problem.
I want to restrict access of anonymous users to a specific collection.
I mean that anonymous users cannot download the bitstreams.

For this purpose, i changed the default-bitstreams-read policy of that 
collection from anonymous users to registered users.

But the result is amazing, its bitstreams are still accessible by anonymous 
users.

when i applied the same policy at item level, it worked well.

any suggestions about this?
