For the time being only Sonar administrators can share some dashboards whereas it should be possible to grant this permission to some super users.
In fact :
- The current Security > Administrators page should be renamed Security > Global Permissions
- A new 'Share dashboards' permissions must be added below the current 'System Administrators' and 'Quality Profiles Administrators' permissions
By default the group 'sonar-administrators' must be associated to this permission.
