Flight SQL Server auth handler

[Philip Moore via user]

I was recently attempting to switch from a middleware approach for handling 
authentication to a Flight SQL server from the Flight SQL JDBC driver.

I have a method that works with middleware – but I wanted to simplify my 
approach.

I attempted to use the build-in Auth handler here: 
https://github.com/apache/arrow/blob/1f42e6d594fab033938cb6ff65fbf521e2b92bc6/cpp/src/arrow/flight/server_auth.h#L54

But when I attempt a connection from a JDBC client – the “Authenticate” 
method’s “incoming” argument is empty for the handshake.

Does the built-in Auth Handler for Flight not work with Flight SQL JDBC clients?

Thanks!
