Re: Cygwin sshd doesn't use domain user names on boot up

Did you install the service by running ssh-host-config?

Yes.

FYI, I had to run ssh-host-config as a domain user. When I first ran it as a local Administrator, the ssh-host-config script printed the following:

Check service dependencies with:
$ cygrunsrv -VQ sshd

You may have to add an additional dependency on netlogon or other AD services to
ensure they are available before sshd starts.

I tried adding netlogon as a dependency to sshd, but didn't see any change in behavior.

If your service start is Automatic, you may also want to change it manually to
Automatic (delayed start), to allow time for network services to be available.

Changing it from "Automatic" to "Automatic (delayed start)" fixed the issue. This is my first time messing with Windows services and didn't see this option initially.

Thanks for the suggestion Brian!
