Describe the bug

aws-sdk-cpp/src/aws-cpp-sdk-core/source/auth/STSCredentialsProvider.cpp

Line 110 in e9d0d24

m_client = Aws::MakeUnique<Aws::Internal::STSCredentialsClient>(STS_ASSUME_ROLE_WEB_IDENTITY_LOG_TAG, config);

The SDK Client Configuration allows user to set caPath and caFIle but STS authentication doesn't use/respect the setting

Expected Behavior

All authentication respects caPath and caFile setting.

Current Behavior

The SDK Client Configuration allows user to set caPath and caFIle but STS authentication doesn't use/respect the setting

Reproduction Steps

In the below code, caFile is pointed to wrong ca file. Yet STS auth should still be able to return a valid token yet the connection to the storage should fail.

Aws::Client::ClientConfiguration config;
config.caFile = "WRONG_CA_FILE";
Aws::S3::S3Client s3_client(config, Aws::Client::AWSAuthV4Signer::PayloadSigningPolicy::Never, false);
Aws::S3::Model::ListObjectsV2Request objects_request;
objects_request.WithBucket("abc");
auto list_objects_outcome = s3_client.ListObjectsV2(objects_request);
