Album permission

Hello.

My gallery installation (latest 2.3) is setup so that every gallery is private (with that i mean that only specific users can access them).

In particular user1 can see "all picture versions" of gallery1, gallery2, gallery3.
user2 can see "all picture versions" of gallery2, gallery4

and so on.

The problem I have is that if I don't enable these users to at least see the root gallery ("display object" permission) they receive a "The action you attempted is not permitted." message when they login to the root site. If, on the other hand, I enable "diplay object" they can see all the galleries, even if can access only the ones they are enabled to.

My question is: is there a way to set permissions in a way that the user see a list and can display only the galleries enabled to her?

Thanks a lot,
Antonio
