Home puts them in their dashboards section, and Screen puts it on the landing page.. Kinda. It worked in that it pushes the dashboard out but when I masquerade as that user, I find that it has just dropped the two dashlets right on top of their login. Meaning the two dashlets completely cover the menu on the side, the "Nagios Fusion Home Views Dashboards Servers Help" ribbon on top, and the default dashboard is still below everything else. It didn't so much replace their landing page as it did drop the two dashlets right on top of their screen.
I tried this with my personal user and a different dashboard, and found the same thing happened. Except this time, it was much worse as this dashboard covered pretty much everything on the entire screen. This doesn't seem like the intended behavior.
