Map IP Addresses to Usernames Using Authentication Portal
When a user initiates web traffic (HTTP or HTTPS) that
matches an Authentication Policy rule, the
firewall prompts the user to authenticate through Authentication
Portal. This ensures that you know exactly who is accessing your
most sensitive applications and data. Based on user information
collected during authentication, the firewall creates a new IP address-to-username
mapping or updates the existing mapping for that user. This method of
user mapping is useful in environments where the firewall cannot
learn mappings through other methods such as monitoring servers.
For example, you might have users who are not logged in to your
monitored domain servers, such as users on Linux clients.
