Using pubkey authentication, the user name Cygwin sees is not the user
name Windows sees.  This is a problem of how pubkey authentication is
achieved, and in which logon session the processes are running.  The
strange Windows behaviour is a long-standing bug (present in NT 4
already), IMHO, which never got fixed (still present in Vista).  This
has been discussed many many times on this list.  Please search the
mailing list archives.

If you want Windows having the same idea of the user name as Cygwin, you
must either use password authentication, or you can take the risk using
the Cygwin developer snapshots and install the cyglsa DLL.  There's a
/usr/bin/cyglsa-config script which helps you to install it.
