We have a role that hides a detail attribute from a dimension by adding in "Dimension data"--> "Advanced"--> "Allowed Member set" the [All] member of this attribute, so not any other member from this attributes can be browsed by the users included in this role.
It works "perfect" so far, but we have realized that the drillthrough action for these users returns an empty rowset. I have seen that there is more people in several places that have the same problem but there are no answers to it. I found that post http://blog.boxedbits.com/archives/38 but I couldn't reproduce his solution.
Does somebody knows about this topic???
