/usr/doc/Cygwin/openssh-3.4p1-5.README states that RSA authentication only
works if sshd runs under a user account (as opposed to the SYSTEM account).
To that end, I've created 2 shell scripts to allow one to "switch" from
running sshd as SYSTEM to running as a user, and visa versa.
These scripts will also fix the '/var/empty' problem, so they are worthwhile
to run once, even if you will never switch.
I haven't tried it, but you could probably even have a user and a SYSTEM
daemon running at the same time, by running one of the daemons on another
port via the -p option.
Attached and inline are the scripts.
I'll also put the latest versions up at http://www.netebb.com/cygwin/.
I'd love to see these incorporated into cygwin's openssh (or at least a user
contribs) package.
I'm not a cygwin wizard, so feedback is appreciated.
