Environment
Novell ZENworks 10 Configuration Management with Support Pack 1 - 10.1
Situation
While installing a second or subsequent server in the zone, ZENworks Install allows you to select port 80 for server to server communication. However, functionality that requires certificates will not work correctly.
Resolution
This is fixed in version 10.2 - see KB 7003225 "ZENworks 10 Configuration Management 10.2" which can be found at https://www.novell.com/support
In 10.2, ZENworks install of second and subsequent servers does not allow the option to disable SSL.
