Maybe the permissions. On some distributions (Fedora,

Debian), the umask is set such that by default any files created are
group writable. However, if the authorized keys file is group writable,
sshd disregards it for security reasons.
To fix this, chmod 600 .ssh/authorized_keys
The permissions of the users's home directory on the destination machine
is also important. If I remember correctly if you set "chmod 700 $HOME",
it does not work anymore.
