/etc/shells and /etc/ftponly no longer work after patching wuftpd 2.6.2

Dear All, 

I configured my wuftp to restrict interactive shell access following the
procedures described in
http://www.landfield.com/wu-ftpd/ftponly/ftponly.html

I began by creating the file /etc/ftponly : 

# cat /etc/ftponly
#!/bin/sh
#
# DO NOT DELETE
#
echo "FTP ONLY"
exit 0
#

And set the permissions correctly : 

# ls -l /etc/ftponly
-rwxr-xr-x   1 root     other         53 Mar  2 16:27 /etc/ftponly

Then created the file /etc/shells : 

# cat /etc/shells
/etc/ftponly

# ls -l /etc/shells
-rw-r--r--   1 root     other         13 Apr 28 16:44 /etc/shells

And this was working fine. I could ftp to the server but not telnet to
it. All well so far. 

I then installed the following patches as mentioned on the wuftp site
http://www.wu-ftpd.org/ : 

Realpath.patch
Connect-dos.patch and 
Skeychallenge.patch

Then re-ran the ./configure, make and make install to recompile wuftpd. 

However, when I try to log in to the new wuftpd, I see the following
error : 

# ftp localhost
Connected to localhost.
220 localhost FTP server (Version wu-2.6.2(2) Thu Apr 28 16:31:45 BST
2005) ready.
Name (gate:pdhillon):
331 Password required for pdhillon.
Password:
530 Login incorrect.
Login failed.
ftp> quit

If I delete the /etc/shells file, then the above ftp works correctly. It
appears therefore that my /etc/ftponly and /etc/shells is not working on
the newly patched version of wuftpd. It was working fine before I
patched and recompiled it. 

Has anyone seen this before or have anything to suggest to resolve it? 

Thanks and regards,
Preet
