I'm using ProFTPd. It has a AuthUsersFile and an AuthgroupsFile
directive that can specify an alternate /etc/passwd file to use...It
would work out _perfectly_, if only it would behave intuitively in
regards to chroot (DefaultRoot). Instead, I have to chroot all of my
virtual users (ftp only, with no accounts at all on the system) in one
ftp directory.. Then, in the virtual directory, place another fake
/etc/passwd in that (but which is not the alternate passwd file), which
is then used to pop logged in users to their "home directory".
