As admin or any user account with Manager or ZenManager role, create a user named acltest. Set a password for the user.
From the user’s Edit tab, make sure that no role is assigned.
Select the user’s “Administered Objects” tab.
From, the menu, select the “Add Device…” item and add an existing device to that user.
The device’s role will default to ZenUser.
Log out of your browser, or open a second browser and then log in as acltest.
Click on the “Device List”.
You should see only the device you assigned to acltest.
Navigate to the device and notice that the Edit tab is not available. This is because you are in read-only mode for this device.
