smbtorture TCONDEV fails to connect to a server running with ADS security as the flags for initiating the connection are not set correctly.
The correct code in torture.c::1238 looks as follows:

----------------------------------------------------------
static BOOL run_tcon_devtype_test(int dummy)
{
	static struct cli_state *cli1 = NULL;
	BOOL retry;
	int flags = 0;
	NTSTATUS status;
	BOOL ret = True;

  if (use_kerberos)
    flags |= CLI_FULL_CONNECTION_USE_KERBEROS;

	status = cli_full_connection(&cli1, myname,
				     host, NULL, port_to_use,
				     NULL, NULL,
				     username, workgroup,
				     password, flags, Undefined, &retry);
