Orchestrator 5: Create a simple XML document = write not allowed

Hi,

I'm going to be crazy , I've upgraded my orchestrator 4.2.1 to 5.0 and now when I want to start the WF (sample provided by default)

"Create a simple XML document" , I have always Permission denied on file 'myfile.xml' , write not allowed

It's the same thing with Find element in document (read not allowed).

I 've changed the default password root:vmware maybe that's why it doesn't work but it will be very curious because on my version 4.2.1 with my password, it works very well...

Thank you in advance
