I have a setup with "xrootd.tls all" and GSI authentication. With that at the server side, a client using "xrdcp --tlsnodata" will get an error [0B/0B][100%][==================================================][0B/s] Run: [ERROR] Invalid response: (source) Obviously the client doesn't know how the server was setup. We may want a better error message, and also guidance on how to setup TLS with GSI authentication (and other authentications). -- You are receiving this because you are subscribed to this thread.
