Thanks for the info - I wasn't aware of passwd -R - just tried it and
it works which is a good relief.
It's a dev lab - anyone with access to the keys is allowed full rights
to the machines - so security not a major concern.
BTW - I had installed cyglsa-config and rebooted and gave the users
the "Act as part of OS" right - but it doesn't work for me. I must be
missing something .....
Thanks again - you've saved me considerable problems!

You didn't mention whether you set up the LSA authentication package
(with /usr/bin/cyglsa-config), or used 'passwd -R' for each user. Did
you try either of those?
The Cygwin User Guide goes into great detail about the methods of
changing user context, in this chapter:
http://cygwin.com/cygwin-ug-net/ntsec.html
The gist of that chapter is this: If you want to be able to login via
ssh as a user that is not running the sshd daemon, you have basically
two options:
(1) Provide a valid Windows password to the sshd daemon, either
interactively (which you obviously don't want to do, since you're
attempting public key auth), or stored statically in the registry via
'passwd -R'.
(2) Use the LSA authentication package. Bear in mind that if you use
this option to avoid giving sshd your password entirely, I believe that
certain privileges are withheld from the logged in user. [I don't
remember exactly what privs are missing in this case... access to
network resources maybe?]
Hope this helps,
-SM
