Hi Jiri,
I created the template and put it in the correct folder location, but I cannot find where to choose the template for the WLC nodes. I read that in order to get the option to choose templates I need to modify "Device Connectivity Method" settings. However; when I browse to that location (file > settings > device connectivity method) I see the attached error message. Then I go to Security settings in the web interface and I do not see any option to enable templates/device connectivity methods. Any ideas?
