Hello,

How to clear the certificate security alarm prompted by the client during user authentication after HTTPS services are redirected to the portal authentication page?

Does anyone know the reason? Thanks!

Hello,

No. The reasons are as follows:

1. After https enable is configured on the device, the device redirects HTTPS traffic (matching the authentication policy) destined for port 443 to the portal authentication page.

2. The device functions as the server to perform TCP handshake and SSL negotiation with the client. During SSL negotiation, the device sends its own certificate to the client. Therefore, the client prompts a certificate security alarm.

3. After SSL negotiation is complete, the client sends an HTTP request, and the device returns a 302 response message for redirection to the portal authentication page. The entire process does not involve SSL decryption. When the device functions as the server to perform SSL negotiation with the client, the sent certificate does not match the URL accessed by the client. Therefore, a certificate security alarm is displayed and cannot be removed.


Glad to help you! Any further questions, let us know.
