Putty: Getting Server refused our key Error

OK, there was a small typo in my key. Apparently when pasting to file the first letter was cut off and it started with sh-rsa instead of ssh-rsa.

nrathathaus – your answer was very helpful, thanks a lot, this answer is credited to you 🙂 I did like you said and set this in sshd_conf:

LogLevel DEBUG3

By looking at the logs I realized that sshd reads the key correctly but rejects it because of the incorrect identifier.
