MAAS, Juju and Openstack are correctly installed and the instance works fine.
Now I’d like to use JUJU to deploy on openstack some apps. I saw this guide and I followed all task but at the end during the bootstrap I receive this error:

ERROR authentication failed.: authentication failed

these commands have being launched on MAAS server, where I’ve installed juju,

   $:juju add-cloud
    Cloud Types
      lxd
      maas
      manual
      openstack
      vsphere

Select cloud type: openstack

Enter a name for your openstack cloud: openstack-cloud

Enter the API endpoint url for the cloud []: http://10.20.81.22:5000/v3

Enter a path to the CA certificate for your cloud if one is required to access it. (optional) [none]: 

Auth Types
  access-key
  userpass

Select one or more auth types separated by commas: userpass

Enter region name: RegionOne

Enter the API endpoint url for the region [use cloud api url]: 

Enter another region? (y/N): n

Cloud "openstack-cloud" successfully added

You will need to add credentials for this cloud (`juju add-credential openstack-cloud`)
before creating a controller (`juju bootstrap openstack-cloud`).

$:juju add-credential openstack-cloud
Enter credential name: richardsith

Using auth-type "userpass".

Enter username: admin

Enter password: 

Enter tenant-name (optional): 

Enter tenant-id (optional): 

Enter version (optional): 

Enter domain-name (optional): 

Enter project-domain-name (optional): 

Enter user-domain-name (optional): 

Credential "admin" added locally for cloud "openstack-cloud".


Maas_$:juju bootstrap openstack-cloud
