Foreman » Smart Proxy

Good morning,

iam Setting up a new Foreman/Puppet infrastructure for provisioning VM's on VMware.
For this i need a DHCP Foreman-Proxy. I set up a new Forman-Proxy with following Details:

- Windows Server 2012 R2
- Foreman-Proxy stable Version 1.11.4
- netsh commands available and the DHCP Administrator Account is running the Foreman-Proxy-Service

The Foreman-Proxy is communicating with a DHCP Server based in Windows Server 2008.
The smart-Proxy.log said:

It seems it is a known Bug Comes if the DHCP Server is based on Windows Server 2008. I read this here (last Entry):
http://projects.theforeman.org/projects/foreman/wiki/ERF12-6899

There is also a Workaround for this, but it seems its for an old Smart-Proxy Version (ok - the post is three years old :) ) ...
I dont have the file dhcp.rb in path lib/proxy/dhcp.rb. This file is in my /module/dhcp path and the file is empty (just first "require 'dhcp/dhcp_plugin".

Did anyone know a Workaround for Smart-Proxy Version 1.11.4 ? ( i have this bug in 11.13 also .. :) ) - seems always been there and not Version specific.

Thanks for your Support.

Best Regards
