Correct, with early implementations of RBAC even if granted every privilege (via role membership), there were features/functions that don't have a mapping.  The dashboard is one of several.  I haven't yet tried with v7.1 (or even v7.0.2.4), but I understand RBAC is getting closer and closer to having the ability to assign feature/function parity of the built-in admin (local) user.
Good Afternoon Everybody,  What I'm trying to do is create a separate username aside from root and admin with all of their functionality. I've created the user and given it all of the available privileges. When I log into the webgui everything seems to be in order except the "Dashboard" tab is grayed out. I couldn't find anything to specifically tell me if this was a tab reserved for the built-in root and admin usernames or if I somehow just messed something up.  I've tried this with local users and domain users. Any insight on this would be appreciated.
Created administrators have no dashboard tab?
