* conv_creds.c (krb524_convert_creds_kdc): loop through all of the

	addresses returned by krb5_locate_kdc, don't just try the first one.
	* krb524d.c (do_connection): check for particular failures of
	decode_krb5_ticket, as well as for messages that are one int long
	(which will eliminate our own error replies.)
