If you're having trouble with switching the user context, it sounds to
me like you're running 'sshd' as 'root' and that's not going to allow
you to change user context by default.  Details on what's happening in
Windows to permit this can be found in the Users Guide here:

<http://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-setuid-overview>

So, you're left with 2 choices:

   1. Rework the permissions of your 'root' user to match that of
      XP's 'SYSTEM' user or the 'cyg_server' user that gets created
      when you run 'ssh-host-config' on post XP OSs plus change all
      the ownerships and permissions on various files and directories
      that 'sshd' accesses to be either 'SYSTEM' or 'cyg_server' (see
      'ssh-host-config' for details).

   2. Just blow away your installation, reinstall, and run 'ssh-host-config'
      and, optionally, 'ssh-user-config', to get things set up properly.

Either should work, though (1) opens a potential security risk by creating
another user on the system with elevated rights.  It also requires you to
understand and configure more yourself.
