cancan breaks scoped mass assignment

Hi all,

I just installed cancan on a new project and found out that it creates some problems with the new scoped mass assignment features of rails 3.2 .

Basically, in my User model I create some attr_accessible attributes in order to avoid users to edit their roles or other sensitive information. From the administration I allow admins to edit those protected attributes by passing :without_protection => true on creation and update of new users.

This works just fine, but adding cancan load_and_authorize_resource to my controller triggers a "Can't mass-assign protected attributes: ...stuff..." . This happens also when using something like[:user], :role => :admin)

I really can't figure out how to solve this, so any help would be very appreciated!

Thanks in advance.
