I think to have found out a BUG into this package, specifically into sshd
service:
if remote user tries to connect to this service, where its home directory
is unaccessible because it doesn't respect right permissions (execution
permission of owner is missed or home directory is missing), he comes
automatically into root folder of chroot.
It's not a bug, it's a feature ;) (c)
I think sshd should have to deny this login or at least sshd_config should
have to contain the option to set this specifc behaviour; for example into
Fedora distributions, there is "DEFAULT_HOME" option in /etc/login.defs
file to permit this behavior.
No.
Yes it's true, I can restrict access to specific users or use PAM module,
but for security reasons I need to make sure myself to restrict access
ONLY to home folder of user.
I also could use PAM modules, but it's only available pam_mkhomedir.so
which creates home folder if this one is not existing; I need
pam_homecheck.so but it's available only as package for OpenSuse.
Suggestions ?
