i think it's need to be cleaned up, it has deleted project, but the relationship of project and user is still exist.
And i find when i have clicked "Modify Users" in "Identity Project" page to add the user to other project, keystone user-get user, it still shows non existing projectID .
Only when "Modify Users" has been clicked in "Identity User" page to choose other tenant, it has changed.
