This is actually somewhat predictable.
Please check the http://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-setuid-overview

Yes, you can do that. Though, the results may be skewed, if you run SSHD
from another user's account. (Other than its normal one, I mean.)

> Thank you again for the ongoing assistance
