CA for mbed tls authentication about azure-c-shared-utility

[SummerSun]

I tried xio_setoption:

XIO_HANDLE tlsio = (XIO_HANDLE)context;
xio_setoption(tlsio, "TrustedCerts", certificates);

Same error.

Hi @SummerSun , we will be investigating this issue soon.

Thanks for reporting it.

@SummerSun - Is this still an issue for you? Also, the authmode should be set to MBEDTLS_SSL_VERIFY_REQUIRED.

@tameraw - Hi, thanks for asking. The issue is still there for me. Have to set to OPTIONAL to workaround it. ewertons said would be investigating the issue, not sure if there's any find?

@SummerSun - I was able to successfully run the tlsio_mbed on an ESP32 using MBEDTLS_SSL_VERIFY_REQUIRED by setting the "TrustedCerts" option with the certs defined here. If you look at the Azure IoT mqtt sample and make sure MBED_BUILD_TIMESTAMP is defined you'll see how and when the cert needs to be set to make it work properly.

I made it to set the trusted certificates to send request and I will give it a try again.
