Comment 0 for bug 1712381

If the owner user and project of a lease are deleted, the OpenStack admin cannot delete the lease. How to reproduce in DevStack:

    source ~/devstack/openrc alt_demo alt_demo
    blazar lease-create --physical-reservation min=1,max=1 1

    source ~/devstack/openrc admin
    openstack user delete alt_demo
    openstack project delete alt_demo
    blazar lease-delete 1

Logs in blazar-m:
