You are right about the greyed out server/host field: it's because the user/password was not correct and it makes sense now that I read your explanation. 
I assumed that the settings were not applied and did not look further.
It worked well to create that general default.properties file but I would like to go a little further, therefor I created a new thread so others can step in and/or learn from it.
I would like to summarize the things I have and it seems I can also create a document.
Will be something for when all is running.
Thanks again for your input!
