Comment 6 for bug 1722580

@Andrew,

Thanks for the input, I have tried that, but looks like some bits are missing. I can use the same credential to get authenticated, but not with juju bootstrap.

## sourced env

$ env | grep OS_
OS_PROJECT_ID=f2b17b339ce0482c9d01b6250005db53
OS_REGION_NAME=MY_Cloud
OS_USER_DOMAIN_NAME=admin_domain
OS_PROJECT_NAME=admin
OS_IDENTITY_API_VERSION=3
OS_PASSWORD=PASSWORD
OS_AUTH_URL=http://172.20.5.49:5000/v3
OS_USERNAME=admin
OS_INTERFACE=public

## verify the credentail

$ openstack token issue
