Comment 1 for bug 1658147

To specify the domain context you are in, you can set it with an env. var or as a flag. Here are some examples:

if you're using a domain named 'default'

$ env | grep OS
OS_PROJECT_DOMAIN_ID=default
OS_REGION_NAME=RegionOne
OS_USER_DOMAIN_ID=default
OS_PROJECT_NAME=admin
OS_IDENTITY_API_VERSION=3
OS_PASSWORD=openstack
OS_AUTH_URL=http://172.16.240.205:5000/v3
OS_USERNAME=admin

or if you're using a non-default domain

$ env | grep OS
OS_PROJECT_DOMAIN_NAME=ibm
OS_REGION_NAME=RegionOne
OS_USER_DOMAIN_NAME=ibm
OS_PROJECT_NAME=my_project
OS_IDENTITY_API_VERSION=3
OS_PASSWORD=humptydumpty
OS_AUTH_URL=http://172.16.240.205:5000/v3
OS_USERNAME=stevemar

Not that you specify either OS_USER_DOMAIN_NAME or OS_USER_DOMAIN_ID, never both. Same goes for OS_PROJECT_DOMAIN_NAME and OS_PROJECT_DOMAIN_ID.
