Why can't I delete my project/tenant from the Horizon dashboard?

Occasionally, you might try to delete a project from the Horizon dashboard but it doesn’t work. When you click Delete Project, the screen refreshes but the project is still listed and no messages are displayed.

To workaround this problem, use the keystone command line client, as in the following example:

keystone tenant-list

(to get a list of tenant IDs)

keystone tenant-delete bfb4e3f449084968ad23d8d3f6f25b3b

(to delete a tenant using its tenant ID)

If you still have trouble, please open a support ticket.
