Chroot: sshd bug ? user redirects to root folder.

["Riccardo Castellani" <ric.castellani@xxxxxxxx>]

I installed openssh-5.6p1 into my Fedora server and I run this service into 
chroot mode.
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.
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 behaviour.
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 ?
