I have two machines with what look like identical cygwin installations
on them, but the Administrator account on one of them doesn't have
super-user privileges. This causes sshd not to have access to
/home/some-user/.ssh (which is restricted to only "some-user") and thus
prevents key-based authentication. Regular password-based
authentication works, so the problem isn't sshd itself. Logging in as
the Administrator and doing "ls /home/some-user/.ssh/*" gives me a
"permission denied" error, which also confirms that the problem is with
the permissions of the Administrator account and not sshd.
The Administrator NT accounts (and Administrators NT groups) seem
identical on the two machines, as are permissions for the C:\cygwin
directory. Both systems had old cygwin installations on them that we
blew away before installing the latest. What am I missing?
1. SYSTEM is the account that sshd runs as, not administrator. It's
the only default account that has permissions to switch user contexts
without authenticating the new user through Windows password mechanism
2. Only the owner of the private key files in .ssh should have permissions
to access these files. Public key files should be readable by anyone.
You'll want to check the permissions on these files relative to the
3. Generally, you should read <http://cygwin.com/problems.html>.
