Allowing and disallowing certain FTP commands

[Jared Yelton]

I am running FreeBSD 4.4 and ftpd.

I have been unsuccessful in trying to determine if there is a way to 
disallow a given user the ability to run MKD via ftp. I am attempting to 
allow a user to upload files but prevent the creation of directories.  I've 
looked through ftpd and inetd manuals and not seen anything that would work.

Any suggestions?
