Angry SSH config/authentication problem


Can someone help me out with this problem. Can't get passwordless authentication using public/private keys to work.

Target server
~/..ssh/ contains authorized_keys file (public key)

Source server
~/.ssh/contains id_rsa

sshd running on both servers

scp -v file <target server>/home/testuser

gives the following and asks for pw (it shouldn't!!):

OpenSSH_3.6.1p2, SSH protocols 1.5/2.0, OpenSSL 0x0090701f

Finally located the sshd log and indicated the following message:

Authentication refused: bad ownership or modes for directory /home/testuser

Changing permissions to 755 on the /home/testuser directory solved the problem.

Thanks,
