Re: sshd authentication question

Ooh, no.  The interesting part happens on the server side.  You must
start sshd under strace.  Create a new service using cygrunsrv, e. g.
called "trace_sshd", which runs `/bin/strace /usr/sbin/sshd -D'.  Run
it instead of the normal sshd service. The output will be automatically
redirected to /var/log/trace_sshd.log.  Be aware that the file might
get *very* big.  And it's a good idea to switch off privilege separation
in your sshd_config file for this.

Another step you can try first:  There's a small chance that an Event
Log entry has been created when the problem happens.  I can't tell you
how that might look like, but it's perhaps worth a try.

Just musing: Is it possible that the /etc/passwd or /etc/group file
gets frequently rewritten on the server machine?  Perhaps something
goes wrong there.  It shouldn't but...
