Although I've not yet tried SSHing into my N900 yet, on my N800 I used to SSH in as root. If I didn't want privileges (which wasn't often), I'd su to user. Perhaps this will help?

ssh user@N900_ip from the Ubuntu machine.
I made sure the folder .ssh is chmod 700 in the N900 and the file /home/user/.ssh/authorized_keys is chmod 600.
(Public authentication works using the N900 as client to login into Ubuntu.)
I also cannot find the ssh logs in the N900 itself.
I thought it would be /var/log/auth.log, as in Ubuntu, but it's not.
Any suggestions?
I apologize it this has been discussed in some other thread.
I assume just like any linux, and even the N800, just cd to .ssh,
that is /home/user/.ssh
open the file known_hosts
and clear the contents.
Do this on both ubuntu and the N900, and when you try to ssh next time it should ask if you want to trust the device and then automatically setup a key again.
Again I don't own an N900 but this works for me on my N800 and ubuntu desktop
***EDIT***
sorry idk how much linux experience you have:
you may have to be root when opening the file to be able to save it.
on N900 idk what editor is available. On N800 I just use leafpad, so from the command line I would type:
sudo leafpad .ssh/known_hosts
and this would open the file to edit in leafpad

Thanks,
I can ssh in as root with password authentication. That is,
I can ssh root@N900_ip and it asks for password and it works. Then as root, I can, as you suggest, su - user, and become "user". But I was trying to login using public keys just because I think it would be more secure in addition to having changed the default root password when I installed openssh server. The next step would be to disable root login.

Couple of things to try:
- on embedded type devices (maybe the N900?), the /var directory is sometimes dumped into the /tmp directory... making the directory you're looking for /tmp/var/log
- also are you confusing password with passphrase?

Mine works. How did you do the copy? Maybe the file
got corrupted.
Does md5sum give the same results on the n900 authorized_keys and the ubuntu id_rsa.pub give the same results?
Try ssh -v
in both directions. The resulting debug output will be
voluminous and maybe obtuse, but any difference may
be a clue.

Have you tried: ssh -vvv that way you'll get a ton of info. If that fails. try setting that on the server and check what it stores in the log.
