Unauthorized Response with Identity-authentication

[thhapke]

I like to migrate a RestAPI client from Python to rust. The authentication runs via certificates.

1. Create Identity: Identity::from_pkcs8_pem(&cert, &key) from 2 pem-files. No complaints

2. Create a client:
   let client = Client::builder()
   .identity(auth)
   .tls_info(true)
   .connection_verbose(true)
   .build()?; -> No complaints

3. Create a request:
   let request: reqwest::Request = client.get(&url)
   .header(header::CONTENT_TYPE, header::HeaderValue::from_str("application/json").unwrap())
   .header(header::HeaderName::from_static(CONTAINER_HEADER),
   header::HeaderValue::from_str(&container).unwrap())
   .query(&query)
   .build()?;

4. Execute request: let response = match client.execute(request).await?;

The header and url looks exactly as it should but I get an unauthorized.

The logging gives no hint, why the authentication fails. Although it might not play any role but I am using macos.

What can I do to test the tls handshake and find the error?

Many thanks

The certificate I am using for the Identity consists of 2 certificates of a cert chain. In addition I have add the root_certificate to the client build, but it has not helped.

The code runs smothly on Linux Ubuntu with openssl. It is a macos issue.
