Sorry; I can't use ver. 0.0.15 software on a production server.  I've 
looked at ProFTPD as an alternative, but it almost seems worse than WU. 
  There's almost always an un-patched exploit for it.

Yeah, I figured that part out.  The difficult part is actually getting a 
file in the format that I need for pam_pwdfile.so

Not one that uses PAM necessarily, just one that can put/generate 
usernames:encrypted_passwords someplace besides /etc/passwd

Here's the problem in a little more detail.  All my web sites have two 
main directories: htdocs and cgi-bin.  Htdocs is owned by user web and 
cgi-bin is owned by user cgi for every site I host.  Any ftp daemon will 
try to run as the user logged in (a user from either /etc/passwd or 
/etc/ftppasswd), but of course the directory I'm chrooting them to is 
owned by either web or cgi.  I don't want to have each site owned by a 
different user; that's a nightmare for more than a handful of sites. 
Also, the ftp program is the only application on the system that uses 
PAM, everything else uses traditional authentication methods (Slackware 
7.0/1).  This problem is really not within the scope of this list, however.
