There's no hint for a specific problem in sshd but it
seems as if you didn't cat your identity.pub file to
authorized_keys. At least the message is identical.
If it would be a permission problem, eg. your authorized_keys
file isn't readable by you, the debug output of ssh -v
would contain:
debug: Remote: Could not open /home/corinna/.ssh/authorized_keys for
reading.
debug: Remote: If your home is on an NFS volume, it may need to be
world-readable
Note that the below output is exactly(!) the same if
your authorized_keys file doesn't exist.
