jailkit/Debian Jessy: No login because of wrong permissions
After adding a shell-user it is not possible to login. After investigation the log tells:
jk_chrootsh: path /var/www/clients/clientX/webX/bin/ is group writable jk_chrootsh: abort, /var/www/clients/clientX/webX is not a safe jail, check ownership and permissions.
Temporary solution is to change permissions like chmod g-w /var/www/clients/clientX/webX/bin/
After that login is OK (no additonal functional tests)
