passwd -R?

passwd -R?

[Alex P]

Hello All!

How do I check that "passwd -R" worked correctly?
I get error messages in Event Viewer when I run it as user (vs "As
Administrator").

Regards,
   Alex P.

You must use it with elevated privileges. Else it wouldn't work at all.

From https://cygwin.com/cygwin-ug-net/passwd.html

"If normal, non-admin users should be allowed to enter their passwords
using passwd -R, it's required to run cygserver as a service under the
LocalSystem account before running passwd -R. This only affects
storing passwords. Using passwords in privileged processes does not
require cygserver to run."

So without the cygserver running, 'passwd -R' is expected to fail
unless it is running in a privileged shell; if you want it to work
without a privileged shell, you have to have the cygserver running as
a service under the LocalSystem account.

I do have cygserver running as "Local System".

My original issue is that cron stopped working after domain user
password reset. Stopped as - it worked fine before.

My first stop was to reset password with "passwd -R", but it did not
fix my cron problem - not running as user (member of local
Administrators group - getting error in Event Viewer), not elevated
("As Administrator").

I suspect some security policies were modified (machine is part of
domain), but I don't know what to check.

Thanks for weighing in.
