Advanced Captive Portal Management: User Limit Protection
Nebula 20.00 introduces "Existing User Protection," a new feature designed to give administrators greater control over simultaneous login limits for Captive Portal accounts.
Understanding Login Behavior
Simultaneous login limits define how many endpoint devices can use a single account at the same time. The default Nebula behavior is to "kick all" existing clients when a new device attempts to authenticate with an account that has reached its limit.

Protecting Active Sessions
By enabling "Existing User Protection," the system keeps all current clients connected and prevents any new devices from authenticating until an existing session expires or is manually cleared. New users will receive a warning message stating that the user has already logged in via other devices.


Monitoring and Customization
Administrators can monitor active portal users by executing the `show users all` command in the AP CLI, which identifies the oldest sessions through their remaining leasing time.

Additionally, the warning message displayed to users can be fully customized by editing the HTML content within the Captive Portal theme customization page.
