ssh asking for password despite keys being awailable,
It also reports Roaming not allowed by server

Not an ssh expert by any means, but when I turn on the same level of verbosity I see
debug1: identity file /home/pschaffn/.ssh/id_dsa type 2
debug1: loaded 3 keys
debug1: Remote protocol version 2.0, remote software version OpenSSH_5.2

Looks like your keys may be version 1 and version 2 is required.

Having the same issue here. I'm just trying to get things working locally at the moment.

Here's -v output:

I've tried various permutations of the configuration, regenerated keys, tried different clients....still nothing. What am I missing?

The recommended reading. That will explain why you should not hijack an old thread, but rather start your own in order to get attention for your question.

That looks more like your key is being rejected by the server side. Check the permissions on the $USER/.ssh directory which should be owned by the user and be chmod 700. The authorized_keys file should also be chmod 700 and owned by the user.
