[ovirt-users] How to disable SSL for oVirt webadmin and userportal??

Dear Sir, When I connecting to the http://ovirt_FQDN/ovirt-engine/ , then I can see link of "User Portal" and "Administration Portal". But when I click either of one link, it will be redirect to http*s*://ovirt_FQDN/ovirt-engine/userportal/?locale=en_US#login or http*s*://ovirt_FQDN/ovirt-engine/webadmin/?locale=en_US#login. I don't want to connect via https, please teach me how to disable SSL for oVirt webadmin and userportal(or not to redirect to https)??
