What is Zenoss?
The Zenoss project provides an integrated, easy-to-deploy and cost-effective opensource alternative for enterprise IT infrastructure monitoring. Unlike the big OSS companies (IBM, HP, CA, BMC, Amdocs) we are able to keep costs down and directly involve end users throughout the world. More details can be found here.
Hm, didn't work for me, so I followed the "domain configuration way". But that's maybe interesting for others: "Accessing Windows Or Samba Shares Using AutoFS".
