Try editing /etc/nova/api-paste.ini and replace:

admin_tenant_name = %SERVICE_TENANT_NAME%
admin_user = %SERVICE_USER%
admin_password = %SERVICE_PASSWORD%

with the actual values (below is assuming you used the defaults from the Folsom doc):

admin_tenant_name = service
admin_user = nova
admin_password = nova
