I just discovered that the problem is cured by using a "-u" option to
ftp, instead of the normal "-n" that ange-ftp uses.

"-u" means "do not auto-athenticate and do not auto-login"

It may be argued that the kerberised ftp should not try to authenticate
when given the "-n" option, for compatibility with traditional ftp, that
is, -n should do the same as -u.

The way the kerberised ftp currently behaves is incompatible with ftp,
and a program using it (ange-ftp) should first test it to see which
version it is.  

Or else ignore those specific 530 messages at startup.
