>Description:
I'm not sure if this is a problem with the documentation, ftpusers(5) and ftpd.conf(5), or with ftpd. According to the man pages, there should be three ways to chroot all ftp users to their home directories.

1) A line at the end of ftpusers:
* allow chroot
The documentation indicates that this should match all users not matched (and therefore denied access) in a previous line, allow them access to the server, and assign them to the chroot class, which defaults to chrooting them to their home directory.
In practice, the * is not interpreted, so it end up not matching any users. If I supply a specific user name, the user is blocked from ftp access, indicating the directive and class parts of the line are not being followed.

2) A single line in ftpchroot:
*
The documentation indicates that this should match all users and chroot them to their home directories (unless an alternative chroot cestination is specified in ftpd.conf).
In practice, the * is not interpreted, so it end up not matching any users. If I supply a specific user name, the user is chrooted correctly.

3) A single line in ftpd.conf:
chroot all %d
The documentation seems to indicate that this should match all users and chroot them to their home directories.
I have not been able to get any results from the chroot command in ftpd.conf
