A User Is Able to See All Cubes Regardless of Restrictions Put in Place.
The security Role applied to a user in SSAS does not take affective on the user in
Pyramid I.E the user can see all cubes regardless restrictions put in place.
The cause of this is likely to be, that the user is a local admin on the SSAS server(s) in use.
Removing the user from the local Administrator group and the Security group assigned to them, should resolve the issue.
If after the above changes, the security is still not applied, verify that the “user” is not part of the server administrator role from within the “Microsoft SQL server Management Studio”, if they are they must be removed.
