Passive registration
You can configure FortiNAC to automatically run logon and logoff scripts and register the host when a user logs on or off a domain. This process allows users to be tracked as they use various hosts on the network. The registration process is not visible to the user. Logon and logoff scripts are provided, but must be customized for your configuration.
To use login or logout scripts, you must be using an LDAP directory for authentication and it must be configured in FortiNAC. See Requirements for an overview on configuring your Directory.
Make sure that Authentication is enabled. See Authentication.
Host registration vs device registration
Host registration associates the host with a user. Device registration has no associated user and the host is registered by its host name. Both types of hosts are displayed in the Host View.
