SSH / Putty : Server refused public-key signature despite accepting key!

[edrom]

SSH / Putty :
Server refused public-key signature despite accepting key!
No supported authentication methods available (server sent: publickey)

Can someone please give me a hint where to look for my mistake setting this up?

I /thought/ that I followed instructions.

Thank you.

Did you get this worked out?

If not we'll need to know more:
Do you have root on the server? can you read sshd_config?
what are the file permissions of the authorized_keys file on the server (should be readable only for your user).
Make sure key type (rsa, dsa) is accepted in sshd_config.
