Subject Re: [DISCUSS] listAll and recursive parameters for BaseListDomainResourceCmd should have default value as TRUE
Date Wed, 09 Oct 2013 00:48:53 GMT
Thanks Alena for the clarification.

If you try ListVMsCmd as a domain admin, if I pass listAll=false, what
should be the expected behavior?
Should he be able to see VMs under his domain but not owned by him? The
current CloudStack behavior will
show all VMs under his domain. This seems contradictory to the meaning of
listAll.

Thanks
