ZLM is Novell’s ZENworks Linux Management product — an add-on to SLES or SLED which gives you a central console from which to easily manage tens, hundreds, even thousands of SUSE or Red Hat servers/desktops.  Novell’s own Mike Friesenegger wrote a nice Cool Solutions article which was just published to help with this customer posed question…

I was asked by a customer to propose a way to change the root password on large number of systems that they manage. My solution was to use the text policy in ZLM 7.2 to modify the password for root.

The assumption that I make in this document is that all of the managed systems currently have the same root password. You should be able to modify this document a bit if you have different root passwords across all of the managed systems.

Here’s how I did it.
