Captive Po rtal Authentication
Captive portal is one of the methods of authentication supported by ArubaOS. A captive portal presents a web page
which requiresuser actio n beforenetwork access is granted. The requiredactio n can be simply viewing and agreeing
to an acceptable use policy, or enteringa user ID and password which must be validated against a database of
authorized users.
You canalso co nfigurecaptive portal to allow clients to download the Dell VPN dialer forMicrosoft V PN clients if
the VPN is to be terminated on the controller. For morei nformationabout t heV PN dialer,see Vi rtualP rivate

Understanding Ca ptive Portal
You can configurecapt ive portal for guest users, whereno authenticati on is required, or for registeredusers who must
be authenticated against an external serveror t he controller’sinternal database.
NOTE:Whi le you can use captiveportal to authenticate users, it does not provide for encryption ofuser data and should not be used
in networkswhere data security is required. Captive portal is most often used for guest access,access to open systems (suchas
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 ArubaOSdi splays login prompts forbo th registeredusers and guests. (You can customize t he default
captive portal page, as described in "Personalizing the Captive Portal Page" on page 25 4)
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.
