Technical Tip : The 'fabric-admin' Username on FortiGate with Security Fabric enabled

When Security Fabric is enabled, along with SSO features, FortiGate will have a 'fabric-admin' username created automatically.

In audit activity, it will raise a flag:

1. It is a legitimate account FortiOS uses for back-end purposes for SSO functionality.
2. It cannot be used to access FortiGate management access.
3. It cannot be deleted or edited
4. It will not affect or impact anything on FortiGate

So this built-in username is not of security concern and can be ignored during audit activity.
