On which device are local administrator login credentials validated?

Local administrator login credentials are validated on the FortiAnalyzer itself. This means that the FortiAnalyzer has its own set of user accounts and stored credentials that it checks against when someone attempts to log in with local administrator access.

When a local administrator tries to access the FortiAnalyzer, the device compares the entered credentials to its internal database. If the credentials match, access is granted, allowing the administrator to manage and configure the FortiAnalyzer.

The other options involve different scenarios where the validation process occurs elsewhere, such as on other devices or authentication servers. However, for local administrators on the FortiAnalyzer, it solely relies on its internal user account management for validating login credentials.
