I just had a session with Aleksey Stukalov and we made a test app and found out, that the problem is the combination of the multitenancy addon and the security module.
The Administrator does not see the tabs “Specific” and “UI” during the role definition when using the multitenancy addon and therefore cannot set the required permissions.
Means, this is a bug.
