I am trying to configure SSHD to allow public key authentication under Cygwin on Windows Server 2012. Currently my problem is access being denied. I have confirmed that my public key is saved as a single line in authorized_keys and authorized_keys2 in the user's .ssh directory. Below you will find the command I used to connedt, the verbose output of my attempt to connect with SSH using my private key, and my SSHD configuration. The private key I'm attempt to use is in RSA PEM format.
I have also tried adding RSAAuthentication Yes to my configuration, but doing cause SSHD to fail on startup.
When RSAAuthentication YES is in the SSHD config I get he below error.
cygrunsrv: Error starting a service: QueryServiceStatus: Win32 error 1062: The service has not been started.
SSH Connection Command
ssh -v -i id_rsa.pem <USER>@<SERVER ADDRESS>
PasswordAuthentication no UsePAM no PubkeyAuthentication yes
