Hello everyone,
Today, I'll tell you how to handle the failure to automatically display the authentication page on an iOS terminal.
Fault Symptom
Failed to automatically display an authentication page on an iOS terminal.
Procedure
1. Check whether the Captive Network Assistant (CNA) bypass function is configured on the AC.
Error-prone configuration:
[AC6605] display current-configuration | include portal captive-bypass enable
Suggestion: Disable the CNA bypass function.
2. Check whether the Portal server pushes an authentication page through HTTPS.
Error-prone configuration: The Portal server pushes an authentication page through HTTPS, but no valid certificate issued by the CA is installed on the server.
Built-in Portal servers push an authentication page through HTTPS. Therefore, an authentication page cannot be displayed on iOS terminals if a built-in Portal server is used.
Suggestion: Check whether the Portal server pushes an authentication page through HTTP. The following uses the Agile Controller as an example.
Choose Policy > Permission Control > Page Customization > Page Customization. Click Advanced setting and check whether Push pages using HTTPS is selected. If so, deselect it or install a valid certificate.
