It looks like a permissions thing. Openssh-4p1-1 *was* working until I
started fiddling with permissions again, trying to get it back to
something more secure. I now have this error at the same place.

setegid 513: Invalid argument

If I authenticate with a password instead, then the ssh client gives

debug1: Next authentication method: password
Greg AT localhost's password: 
debug1: Authentication succeeded (password).
debug1: channel 0: new [client-session]
debug1: Entering interactive session.
Last login: Tue Apr  5 12:36:31 2005 from localhost
setgid: Invalid argument

I would guess 513 is being rejected as a group ID. Does cygwin create
the None group or is it a built-in?
