Centralized Web Authorization

Deployment Strategy

Centralized Web Authentication (CWA) provides the URL for the captive portal dynamically through RADIUS attributes, following the successful authentication over 802.1x. CWA can integrate with both an ExtremeControl captive portal server and a Cisco® ISE captive portal server.

The configuration required on ExtremeCloud IQ Controller is the same regardless of the captive portal server used:

On ExtremeCloud IQ Controller:
  1. Configure a AAA Policy, defining the RADIUS server, then reference that AAA Policy on the CWA captive portal network configuration.

    The RADIUS server in the AAA Policy is the authentication server that sends the redirection attribute back to ExtremeCloud IQ Controller. You only need the role name on ExtremeCloud IQ Controller to match the Filter-ID sent in the RADIUS-Accept.

  2. Configure a CWA captive portal network.
  3. Configure a Redirect Policy Role that includes at least one redirect rule.
When integrating with an ExtremeControl server, we use the ExtremeControl rules engine. The rules engine assigns the policy Unregistered to the redirection and assigns the policy Enterprise User when authenticated by the captive portal:
  1. Map the redirection policy that you created on ExtremeCloud IQ Controller to ExtremeControl.
  2. Create an allow policy on ExtremeCloud IQ Controller and map it to ExtremeControl.
When integrating with a Cisco® ISE captive portal server:
  1. Configure an Authorization Profile that references the policy role configured on ExtremeCloud IQ Controller.
  2. Configure an Authorization Policy that references the Authorization Profile.

    The Authorization Policy will include three profiles: the Redirection Profile, an Allow Profile, and a Deny Profile.

    Note

    Note

    The Allow Role will take effect once the user has been successfully authenticated to the network. From the clients list on ExtremeCloud IQ Controller, you can view the client that authenticated the network. The Allow Role is listed in the Role column.
  3. The Authorization Profile generates the following attribute details:
    • The redirection policy role.
    • The redirection URL.
