Casper,
Thanks for the lead but not quite clear enough for me, yet.
The login-class approach looks perfect but when I check
/etc/login.conf - the sample file does not include any
chroot entries. What does ftp-chroot have to do with access to the
password files?
We are using pine 4.03. I checked the man pages and S/Config and
could not find 'operating-dir'
pine -operating-dir $HOME
Appreciate the lead, need to squeeze out a bit more information <g>.
Thanks.
Best Regards
jeff

use
pine -operating-dir $HOME
option of the pine , and put in the user's login-class :ftp-chroot:
option ....
