Cron can't switch user context

[Andrey Repin]

Greetings, Brian Inglis!

The one Q&A should have get you started: since Cygwin 3.1 (IIRC, may be
earlier), the core was changed to use LocalSystem account and some new(-ish)
facilities only available in Windows 7 and up to rebuild auth user token
without using CygLSA or what not.
This affecting SSHD, Cron and any other Cygwin daemon dealing with user
authorization.

>> We would be very glad if you could give us some hints how to solve the problem.

>> P.S. Please note that /var/log/cron.log and /home/Administrator/cron.log are 
>> both empty, so we didn't attach them.

> Don't forget to either set PATH to scripts in crontab or set for system before
> cygrunsrv starts cron as a Windows service.
