I am finding an open source/free network inventory management system (keeping track of desktops/servers/printers, like their warranty) which allows us to create different views or permissions for different users. For example, Regional users can only view/edit the inventory in their region.
I have looked into some tools like Spiceworks, Open-AudIT, OpenNMS. It seems that either you create an administrator with full controls over everything, or you alert some other users when there are incidents.
Could someone suggest a tool with such user-permission on view/edit?
P.S. We already have tools like SCCM to discover the devices. In other words we are looking for a presentational interface for browsing the device information we had. Also the device information are stored in SQL Server, thus the software should be running in Windows.
