After emerging openssh (the exploit fix) into my Gentoo Linux system, Only root is able to ssh into the system.
There is a similiar issue with xlock. I am not sure if they are 100% related, but I was looking at a pam issue in relation to accesing the shadow file. The xlock issue is that pwdb_chkpwd cannot find the password (cannot access the shadow file ?). I have not found anything concrete yet.
Do you have a shell set in /etc/passwd?
Added /bin/bash to the users line in /etc/passwd.Everything works correctly for me now.Pieter Van den Abeele
