When authenticating with third-party credentials such as Facebook or Google, the ExtremeCloud IQ Controller unregistered access policy must allow access to the third-party site (either allow all SSL or make allowances for third-party servers). The Portal Configuration must have the specific site registration enabled and include the Application ID and Secret for the third-party site.
Third-party registration for networks redirecting HTTP traffic to the captive portal using DNS Proxy requires additional configuration.
Note
With an availability pair, when configuring authentication in the portal, specify the URI (Uniform Resource Identifier) for both the Primary and Secondary appliance.
