Hey there, I installed the latest version of openstack with RDO kilo. and did all the necessary configuration to make heat work. I used this command to generate new credentials for heat as I had found the error authorization failed in my heat-engine.log : $ heat-keystone-setup-domain \ --stack-user-domain-name heat_user_domain \ --stack-domain-admin heat_domain_admin \ --stack-domain-admin-password heat_domain_password My problem is that I still have the same problem even if I had updated my heat.conf with these information and rebooted my openstack controller and compute. any ideas? 2015-05-26 13:48:40.380 5046 DEBUG keystoneclient.session [-] Request returned failure status: 401 request /usr/lib/python2.7/site-packages/keystoneclient/session.py:396 2015-05-26 13:48:40.380 5046 DEBUG keystoneclient.v3.client [-] Authorization failed. get_raw_token_from_identity_service /usr/lib/python2.7/site-packages/keystoneclient/v3/client.py:279 2015-05-26 13:48:40.381 5046 ERROR heat.common.keystoneclient [-] Domain admin client authentication failed 2015-05-26 13:48:40.405 5046 INFO heat.engine.stack [-] Stack CREATE FAILED (scaleup_down): Authorization failed. 2015-05-26 13:48:40.406 5046 INFO heat.engine.service [-] Stack create failed, status FAILED 2015-05-26 13:48:40.408 5046 DEBUG heat.engine.stack_lock [-] Engine eb952064-9ddf-498a-b60a-5bd725fdbbef released lock on stack c4dfd3f5-405e-439c-89ba-b65f8add7e74 release /usr/lib/python2.7/site-packages/heat/engine/stack_lock.py:132
