Troubleshooting
The following lists some ideas for troubleshooting :
If /var/log/sshd.log says “Privilege separation user sshd does not exist,” then either turn off privilege separation in /etc/sshd_config, or create the “sshd” account (e.g., with Cygwin’s useradd command).
Run filemon from the command line, and look for accesses to the ~/.ssh directory.
In the Local Security Policy administrative tool, turn on auditing for object access: this is found under Local Policies/Audit Policy. Set it to audit both success and failure. Then select the ~/.ssh folder and enable this auditing for all accesses to the folder and its contents (Properties/Security/Advanced/Auditing).
