ProFTPd: PathDenyFilter doesn't work

[sci2tech]

Code:

ftp> rmdir cgi-bin
250 RMD command successful
ftp> mkdir cgi-bin
257 "/cgi-bin" - Directory successfully created

If you try rmdir /cgi-bin it wont work because regexp expect that first character is /. If you drop this character it wont work rmdir cgi-bin but it will work rmdir /cgi-bin. if you put a ? after / (PathDenyFilter "^/?(backups| ) none of this will work.
But consider that one user have a cgi-bin (or more usual a logs dir) in other folder. Then he will be able to delete only with rmdir /path/to/folder/cgi-bin but not with
cd /path/to/folder
rmdir cgi-bin
Use version that suit your need . Or wait until http://www.isp-control.net/ispcp/ticket/1080 is fixed.
