Public bug reported:

The problem is that keystone endpoint urls from AVAILABLE_REGIONS
settings has suffix defining which keystone version should be used, and
that version does not always match with the version inside the url
returned from keystone catalog.

More concrete example (local_settings.py snippet):

OPENSTACK_API_VERSIONS = {
   "data-processing": 1.1,
   "identity": 3,
   "volume": 2,
}

OPENSTACK_HOST = "192.168.0.1"
OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3"; % OPENSTACK_HOST
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "_member_"

#For multiple regions uncomment this configuration, and add (endpoint, title).
AVAILABLE_REGIONS = [
   (OPENSTACK_KEYSTONE_URL, '7.0 lab'),
   ('http://192.168.10.1:5000/v2.0', '7.0 sahara lab'),
]

Once I log in to '7.0 lab' Keystone endpoint here
https://github.com/openstack/django_openstack_auth/blob/1.4.0/openstack_auth/views.py#L124
region is being set to 'http://192.168.0.1:5000/v2.0' which causes
'region_name' on the next line to become None (since this url is not
found inside 'regions' dict, see line above). See results on a
screenshot below.
