SSH Login From User With Empty Password

Hello list,

on a CentOS 6.4 machine I’m creating accounts with empty passwords. Each user’s public key is located in /.ssh/authorized_keys.

When trying to SSH into that machine, following error message is displayed:
Permission denied (publickey).

In /etc/ssh/sshd_config I’ve set:
PasswordAuthentication no UsePAM no

If I set a password for the users, the public key auth works without any problems.

Could anyone tell me what I’m missing here?


Thanks Michael
