Open local WebI report logon issue

Hi all,

I have a small issue on a BO 4.1 migrated (from 3.1) platform. When a user opens a local WebI Report the logon prompt doesn't automatically show itself asking the user to authenticate so the user have to manually open the logon.

There wasn't this behavior on the original BO 3.1 platform. Is there any kind of options about this ?

Thanks,

Michele
