I just noticed that I'm having the exact same problem, and
thought I'd add a few details.

ftpd intercepts the command so you can restrict your users from
creating directroies even in the directory they own. If the
user has permission from ftpd to create directories, then the
permissions/ownership of the actual directory comes into play.
When the mkdir fails because of permission on the actual directory,
the error message is:
550 test: Permission denied.
When the mkdir fails because the user has not beengiven mkdir permision
in the ftpaccess file, the error message is:
530 test: Permission denied. (Mkdir)

The "dirs|nodirs" option to the upload statements in the ftpaccess
*is* the config option. It just doesn't seem to be working.
Question: Do you have those users set up as "guest" acounts
in the ftpaccess file?
For example, here's what I'm doing in my ftp access file to give
ftp only user "bob" access:
===
upload /home/ftp /pub/bob yes bob bob 0644 dirs
upload /home/ftp /pub/bob/* yes bob bob 0644 dirs
guestgroup bob
===
This setup allowed bob to create directories when I was running wu.ftpd
under Slackware 2.3; bob can no longer create directories with the ftpd
from RedHat 4.0.
While I'm on the subject, I noticed that I also get the following
message showing up in the syslog every time a guestgroup user
(but not anonymous or real users) logs in or exits:
ftpd[1511]: open of pid file failed: No such file or directory
I have
class all real,guest,anonymous *
in the ftpaccess file, and /var/run/ftp.pids-all exists
and is readable.
Possibly related, ftpwho appers to only show anonymous users and
not real or guest users, even though they're all in the same class.
Anyone out there actually have this working under RedHat 4.0?
And if so, how do you have it configured.
