I have a problem in ssh login without password
 
Systems:  vmware-centos 5.2:  192.168.0.4  vista copssh: 192.168.0.2

[192.168.0.4 $] ssh-keygen -t dsa
[192.168.0.4 $] scp -p id_dsa.pub tester at 192.168.0.2:.ssh

[192.168.0.2 $] cat .ssh/id_dsa.pub >> .ssh/authorized_keys
[192.168.0.2 $] chmod 700 .ssh
[192.168.0.2 $] chmod 600 .ssh/authorized_keys

[192.168.0.4 $] ssh id at 192.168.0.2
Permission denied (publickey).

But with password, I can connect to 192.168.0.2.

The sshd_conf is as follows;
 

192.168.0.4(centos 5.2) sshd_conf:

What am I wrong?
Any comment would be appreciated.
