Captive Portal Authentication
Captive portal authentication allows a wireless client to authenticate using a
web-based portal. Captive portal authentication can be done over SSL, but
provides no encryption for user data once authentication has taken place.
Therefore, it should be used in environments where encryption is not required,
such as when providing Internet access for guest users. To configure captive
portal authentication, navigate to
Configuration > Security > Authentication
Methods > Captive Portal
, as shown in the figure below. Additional captive portal
customization may be done under MaintenanceÆCaptive Portal (see “Captive
Portal Maintenance” on page 555).
FIGURE 5-21 Captive Portal Authentication
Available configuration parameters are:
Authentication Enabled – Enables or disables captive portal authentication.
Default Role – If a client authenticates using captive portal, and the
authentication server does not provide role information, the default role will be
given to the client.
