[ovirt-users] How can I Disable console Single Sign On by default

Dear all. I'm trying to setup an oVirt environment able to provide VMs to a small number of users. I'm just using the "internal" domain and I defined some users and groups using ovirt-aaa-jdbc-tool. Everything seems to work, the users cal log-in into the VM portal and they can create VM. The problem comes out when I try to access the VM console: in order to be able to open the noVNC console, I need to set Disable Single Sign On on the console settings of the VM. But this is only possible using the Administrator portal and I couldn't find a way to do it "as user". How can I allow users to open the noVNC console from the VM portal? Is there a way to set Disable Single Sign On by default? Thanks a lot Riccardo
