Greetings everyone.
Request your help one more time. I've been struggling to understand why the tasks like start,stop,reset on virtual machines fail with the error: ERROR -- evm: [Handsoap::Fault]: Handsoap::Fault { :code => 'ServerFaultCode', :reason => 'Permission to perform this operation was denied.' }
Method:[block (2 levels) in class:LogProxy]

I could certify that the user has permissions over the objects (at least using a common CURL REST API operation allow to the authenticated user execute those operations), but I understand that manageIQ use itself soap client. Then I would like to know if I need to add additional permissions to the user. Also I read the documentation to add a VMWare provider, and saw that I should authenticate to the ESX hosts. That step has not been executed, but I would like to understand whenever execute is mandatory and Why?

Thanks
