Captive Portal Authentication

Captive portal is one of the methods of authentication supported by ArubaOS. A captive portal presents a web page which requires user action before network access is granted. The required action can be simply viewing and agreeing to an acceptable use policy, or entering a user ID and password which must be validated against a database of authorized users.

You can also configure captive portal to allow clients to download the Dell VPN dialer for Microsoft VPN clients if the VPN is to be terminated on the controller. For more information about the VPN dialer, see Virtual Private Networks on page 271.

Understanding Captive Portal

You can configure captive portal for guest users, where no authentication is required, or for registered users who must be authenticated against an external server or the controller’s internal database.

NOTE: While you can use captive portal to authenticate users, it does not provide for encryption of user data and should not be used in networks where data security is required. Captive portal is most often used for guest access, access to open systems (such as public hot spots), or as a way to connect to a VPN.

You can use captive portal for guest and registered users at the same time. The default captive portal web page provided with ArubaOS displays login prompts for both registered users and guests. (You can customize the default captive portal page, as described in "Personalizing the Captive Portal Page" on page 254)

You can also load up to 16 different customized login pages into the controller. The login page displayed is based on the SSID to which the client associates.
