Authorizing FortiGate NVAs on FortiManager
FortiGate NVAs are grouped together in FortiManager based on the FortiGate Name Prefix specified in Azure when you deployed the FortiGates.
Before you can use FortiManager to configure the FortiGate NVAs, you must authorize FortiManager to manage the devices.
On FortiManager, ensure you are using ADOM version 7.2 or later. The authorized FortiGate NVAs must be placed in ADOM version 7.2 because ADOM version 7.2 is required to automatically group the FortiGate NVAs into a device group.
To authorize FortiGate NVAs on FortiManager:
- On FortiManager in the root ADOM, go to Device Manager > Device & Groups, and select the Unauthorized Devices list. The FortiGate NVAs are displayed in the content pane.
- In the content pane, select all FortiGate NVAs, and click Authorize.
The Authorize Device dialog box is displayed.
The FortiGate NVAs are grouped together with the name of the NVA from Azure. In the following example from FortiManager, the device name is demovwan-xz3czsyqfit200000. 
The following example in Azure shows the name
demovwan-k3q3jr36urmi6 .
- Select an ADOM that is version 7.2, if ADOMs are enabled, and click OK.
Ensure that you select the ADOM version 7.2. For example, FortiOS 7.2.5 requires FortiManager 7.2.3 or higher with ADOM 7.2.
The authorized device group of FortiGates is displayed.
Depending on the ADOM selected during authorization, you may need to switch to a ADOM to see the authorized devices.
