I gave the permission "use admin toolbar" to a role theat doesn't have the permission to access every configuration page, e.g. not for the user account configuration.
A user of this role has access to the main menu items of the management menu, that are according to his permissions. That's cool, but he can see all the submenu items, even those for which he has no access. When he follows the menu link he gets:
"No Administration objects available."
It would be better if he only could see the submenu items for which he has access to configure.
Closed: won't fix
