    Hi all.

    I try run this chroot-stuff for sftp, since I shall provide
    ftp access to some users, who should be restricted to their directories.

    what I did ...

    I compiled openssh-3.9 four or five times using different patches
    for session.c, always building this chroot environment with all the
    libraries and its own directorie-tree. Most of them were dealing with
    this magicpoint thing like "/./" and one of them wanted the chrooted
    user to belong to a group like "shacc"

    After all I tried out this scponly stuff, which seemed to work fine
    since there is a setup_chroot.sh - shell-script building the chroot.

    my problem ...

    All attempts were leading to the same problem. I'm not able to authenticate
    a chrooted user in any of this cases. Neither when using the private/public
    key pair (one, that works fine for a not chrooted user), nor if trying the
    password authentication, though I copied the passwd, shadow, group to his
    /homedir/etc directory.
    In this scponly-homepage, where they explain how this works, they say
    the authentication-stuff will be done by openssh in the first step and than,
    afterwards in the second step the user will be chrooted.

    Hope somebody has a hint, how I can deal with this problem.

    thanks in advance
