The wu-ftpd-2.5 "update" rpm (presumably applies to rh 6.0
as well, but 5.2's what I've got running at the moment)
introduces anomalous behaviour in the case of prohibited
anonymous ftp login, compared to the previous "update" rpm
The old behaviour (illustrated second, below) is far
superior. Both machines lack the "ftp" user in the password
file (but ftp is used to user accounts from within our
network which we believe is secure).

This issue has been forwarded to a developer for further action.
There were numerous aguments about people probing various sites for
valid accounts using ftp, so the maintainers changed that to have a
more conservative behavior.
There are pros and cons for either side...
