One more permissions problem that can bite you. The home directory
that the .ssh directory is in can nor have too permissive permissions.
755 should work but 777 for example will not. Now ssh-keygen -t dsa
produces a key for ssh 2 not ssh 1. As I understand it the file to put
the key in might be either authorized_keys or authorized_keys2
depending on the version of OpenSSH installed. But putting the key in
authorized_keys is certainly something to try.
