I've been searching the archives to find a way to eliminate the display of the link to the dashboard for authenticated users. I find this item in the issue tracker that includes code to prevent a link when no access exists. http://orchard.codeplex.com/workitem/18232
Working off 1.5.1 and I see this code is included in \Orchard\Core\Shapes\Views\User.cshtml
None the less, when logged on via a account that has no role assigned (that _should mean authenticated, right?). The Edit Roles screen has enabled only 'Add comment' and 'Access site front-end' enabled. I'm still seeing the Dashboard link and it still displays
a page with the message 'Access Denied'.
I've created a new role with _no permissions_ enabled and get the same behavior.
