All images have no Project

I deployed glance (liberty) on Debian Stretch from Debian's official repo.
Now glance works, I can upload images and start VMs. But when user create a image, or take a snapshot, the image has no 'Project' attribute. Which makes the image invisible for anyone other than admin.

For example, the following is a snapshot taken from a normal user:

$ glance image-show 6ba66f20-2256-4cec-a996-1af9e56ecea0

The owner_id is the correct tenant id that the VM belongs to. But the snapshot is invisible in dashboard for that user.
