Certain user roles, specifically guests and external vendors need to be restricted from seeing floor plans. The issue is coming up a lot for Workplace Portal, but is really a system-wide need. There should be the ability to hide floor plans from defined users roles. Either through security groups or an application parameter.

Then, users without floor plans, need to default to a list of rooms for Booking Conference Rooms, Desks and Service Requests. In other areas of Archibus, they would either not see the button to show a floor plan or clicking the button would show a generic message saying they do not have permission to view floor plans.
