Open Stack

hi guys,I'm running openstack newton. I followed official installation guide for ubuntu here https://docs.openstack.org/newton/install-guide-ubuntu/. I successfully configured up to horizon and and I have couple of VMs running in my cloud. Now I'm trying to install cinder. After installing cinder in controller node, I issued "cinder service-list" command and I'm getting following error. ERROR: 'unicode' object has no attribute 'get'
When checking at cinder-api.log it shows as below
2017-06-07 16:41:06.713 2509 WARNING keystonemiddleware.auth_token [-] Identity response: {"error": {"message": "The request you have made requires authentication.", "code": 401, "title": "Unauthorized"}}2017-06-07 16:41:08.894 2509 WARNING keystonemiddleware.auth_token [-] Identity response: {"error": {"message": "The request you have made requires authentication.", "code": 401, "title": "Unauthorized"}}2017-06-07 16:41:08.895 2509 CRITICAL keystonemiddleware.auth_token [-] Unable to validate token: Identity server rejected authorization necessary to fetch token data2017-06-07 16:41:08.898 2509 INFO eventlet.wsgi.server [-] 10.0.60.10 "GET /v2/8d6d90523e0140eb9ed3784718ed1345/os-services HTTP/1.1" status: 503  len: 401 time: 2.3119080

Also keystone-wsgi-admin.log shows following warning
WARNING keystone.common.wsgi [req-9292b165-202f-43b4-acdd-da07f0b9e050 - - - - -] Authorization failed. The request you have made requires authentication. from 10.0.60.10

I used admin token as below,

export OS_PROJECT_DOMAIN_NAME=defaultexport OS_USER_DOMAIN_NAME=defaultexport OS_PROJECT_NAME=adminexport OS_USERNAME=adminexport OS_PASSWORD=xxxxxexport OS_AUTH_URL=http://controller:35357/v3export OS_IDENTITY_API_VERSION=3export OS_IMAGE_API_VERSION=2export OS_VOLUME_API_VERSION=2

I'm trying to figure out this issue since couple days. I would really appreciate if you can help me on this issue.
Thank you in advance.
Best Regards,Ash
