Bug Description

Here's what i did:

1) add an image to glance with is_public=true as an admin
2) run nova image-list as non-admin user to verify image is visible
3) try to nova image-delete as non-admin user -- results in a 404

If i ask for the image through the glance cli, it is there (public and unprotected) with the admin tenant as the owner. Trying to delete it as the admin will succeed.

This should result in a 403 if the user attempting to delete it doesn't have permission, returning a 404 is just mean.

Additionally, we should only return 403 if the image is visible to the user. 404 is still appropriate if the user can't see the image

    Handle access restriction to public unowned image

    Fixes bug 923941. Now we can return a 403 rather than a 404
    if we reject a modification for a public image.

I'm not 100% sure this is fixed - using latest devstack (8d87ca05330d050561611fcc43cfa941a340d13a)

I have an image uploaded as admin user/admin tenant.

I can see that image as the demo user/demo tenant

# env|grep OS

# glance show 70859aed-6ede-4e26-a525-74b5d04cd26f

If I try to delete it, I essentially get a 404

# glance delete 70859aed-6ede-4e26-a525-74b5d04cd26f
Delete image 70859aed-6ede-4e26-a525-74b5d04cd26f? [y/N] y
No image with ID 70859aed-6ede-4e26-a525-74b5d04cd26f was found

As admin user/tenant I can delete it no problem

Crap, I only fixed it for access directly to the registry api. I'll push up a fix for it.
