> I started a server with --rpc_authentication=required, but didn't specify a keytab. The server started, but when I try to connect to it, the server abruptly disconnects the client (so the client gets a network error and retries). The server spews the log:
> {code}
> 0316 08:16:36.271464 (+    39us) negotiation.cc:281] Negotiation complete: Invalid argument: Server connection negotiation failed: server connection from 127.0.0.1:55920: RPC authentication (--rpc_authentication) may not be required unless Kerberos (--keytab_file) or external PKI (--rpc_certificate_file et al) are configured
