@ann,
You may need to rerun the tasks in the keystone portion of the playbook. You should be able to reexecute these by passing --tags keystone
when launching the playbook. One of the tasks in there is to create the service project.
You could also try to manually execute that step in a terminal to see if there is some other output given. Just make sure you source admin-openrc.sh first.
Regards,
Tom
