Configuring the Wireless AP 295
5. Regardless of whether you selected a global authentication server in Step

Purple WiFi. On the Security > External Radius Page, in the RADIUS
Attribute Formatting section:
• Set Called-Station-Id Attribute Format to Ethernet MAC.
Purple WiFi Client Login Process Details
This is an overview of the interaction between the AP and Purple WiFi when a
client connects. The client is not aware of any of these details and is led through
the process by Purple WiFi’s simple interface.
1. A client (smartphone, iPad, etc.) connects to an SSID at a Purple WiFi
customer site.
2. The SSID is configured for WPR. As soon as the client opens a browser, it
is redirected to the configured Purple WiFi portal page that was
configured in the AP External Login page, via the Redirect URL.
3. The AP contacts the Redirect URL along with the AP’s MAC address
(Ethernet MAC). This is used to match the Purple WiFi customer site
against a database of AP MAC addresses managed by Purple WiFi, which
delivers a customized splash page.
4. The Purple WiFi splash page prompts the end user to log into a social
media site.
5. Upon successful authorization at the social media site, a record is then
created in the Purple WiFi (External RADIUS) database for the client.
6. The Purple WiFi splash page then redirects the browser back to the login
script on the AP along with the authentication information (username/
password), and the AP then performs an external RADIUS authentication
request against the Purple WiFi RADIUS servers (as configured on the
AP).
