   Update on the first issue (see 
[discussion](https://lists.apache.org/thread/66zd5k3l63vrztjjmgzdh3xm389cbkbk)).
 It looks like that the expectation would be to set the authorization header on 
the response. I took a look at the `FlightSqlServiceClient` and it looks like 
the authorization header is indeed expected in the handshake response:
   
   ```rust
         let resp = self
             .flight_client
             .handshake(req)
             .await
             .map_err(|e| ArrowError::IpcError(format!("Can't handshake 
{e}")))?;
         if let Some(auth) = resp.metadata().get("authorization") {
             let auth = auth
                 .to_str()
                 .map_err(|_| ArrowError::ParseError("Can't read auth 
header".to_string()))?;
             let bearer = "Bearer ";
             if !auth.starts_with(bearer) {
                 Err(ArrowError::ParseError("Invalid auth 
header!".to_string()))?;
             }
             let auth = auth[bearer.len()..].to_string();
             self.token = Some(auth);
         }
   ```
