Running "net start sshd" in my own shell has the effect of starting
the sshd Windows service that was installed by ssh-host-config. I
think it is equivalent to starting the service using the Windows GUI.

Ah, you're close. Looking in /etc/passwd I see that myid's gid, which
should be the number for "Domain Users" listed in /etc/group, is a
different number. I think I know how that happened, but I will spare
you the details. Putting the correct gid in /etc/passwd fixed the
problem. Thanks.
