Configuring External Captive Portal Authentication Using ClearPass Guest

You can configure Instant to point to ClearPass Guest as an external Captive Portal server. With this configuration, the user authentication is performed by matching a string in the server response and RADIUS server (either ClearPass Guest or a different RADIUS server).

Creating a Web Login page in ClearPass Guest

The ClearPass Guest Visitor Management Appliance provides a simple and personalized user interface through which operational staff can quickly and securely manage visitor network access. With ClearPass Guest, the users can have a controlled access to a dedicated visitor management user database. Through a customizable Web portal, the administrators can easily create an account, reset a password or set an expiry time for visitors. Visitors can be registered at reception and provisioned with an individual guest account that defines their visitor profile and the duration of their visit. By defining a Web login page on the ClearPass Guest Visitor Management Appliance, you are able to provide a customized graphical login page for visitors accessing the network.

For information on setting up the RADIUS Web Login feature, see the RADIUS Services section in the ClearPass Guest Deployment Guide.

Configuring RADIUS Server in Instant UI

To configure Instant to point to ClearPass Guest as an external Captive Portal server, perform the following steps:

1. Select the WLAN SSID for which you want to enable external captive portal authentication with CPPM. You can also configure the RADIUS server when configuring a new SSID profile.
2. In the Security tab, select External from the Splash page type.
3. Select New from the Captive portal profile drop-down list and update the following fields:
a. Enter the IP address of the ClearPass Guest server in the IP or hostname field. Obtain the ClearPass Guest IP address from your system administrator.
b. Enter /page_name.php in the URL field. This URL must correspond to the Page Name configured in the ClearPass Guest RADIUS Web Login page. For example, if the Page Name is Aruba, the URL should be /Aruba.php in the Instant UI.
c. Enter the Port number (generally should be 80). The ClearPass Guest server uses this port for HTTP services.
d. Click OK.
4. To create an external RADIUS server, select New from the Authentication server 1 drop-down list. For information on authentication server configuration parameters, see Configuring an External Server for Authentication.
5. Click Next and then click Finish.
6. Click the updated SSID in the Network tab.
7. Open any browser and type any URL. Instant redirects the URL to ClearPass Guest login page.
8. Log in to the network with the user name and password specified used while configuring the RADIUS server.
