I've been trying to solve this for a while, but I'm admittedly quite stumped.
I just started up a new server and was setting up OpenSSH to use key-based SSH logins, but I've run into quite a dilemma. All the guides are relatively similar, and I was following them closely (despite having done this once before). I triple checked my work to see if I would notice some obvious screw up - but nothing is apparent. As far as I can tell, I haven't done anything wrong (and I've checked very closely).
If it's any help, on my end I'm using Cygwin and the server is running Ubuntu 12.04.1 LTS.
Anyways, here is the output (I've removed/censored some parts for privacy (primarily anything with my name, website, or its IP address), but I can assure you that nothing is wrong there):

What can I do to resolve my problem?
