[GeoNetwork-users] harvesting policy problem

hi to all,
i have a problem with harvesting system, could anyone help me?
This is the problem:
on a node A:
i insert as user1 a metadata item1 with the pdf file,
in node B:
if i login as user2 i can see the harvested metadata item, but i can't see the download button

user1 and user2 belong to the same group = groupX

in the node A when i inserted the item1 i put as privileges
for groupX publish, download, interactive map

in the harvest configure page in node A for node B (node A and B are geonetwork node) i have
as remote group = groupX with 'copy' policy.

As result when i run an harvest in node B,
and login as user1 or user2 i don't see the download
botton, i'm non able to retrive the privileges.

Which is the problem?

Could anyone help me?

Regards
Eugenio
