    Here is how I am authenticating using openstacksdk:

from openstack import connection
from openstack import profile
from openstack import utils

def _create_connection(self, cloud_params, configobj):

        auth_args = {
            'auth_url' : cloud_params['OS_AUTH_URL'],
            'username' : cloud_params['OS_USERNAME'],
            'password' : cloud_params['OS_PASSWORD'],
            'project_name' : cloud_params['OS_PROJECT_NAME'],
            'user_domain_name' : cloud_params['OS_USER_DOMAIN_NAME'],
            'project_domain_name' : cloud_params['OS_USER_DOMAIN_NAME'],

        prof = profile.Profile()
        prof.set_region(profile.Profile.ALL, cloud_params['OS_REGION_NAME'])
        prof.set_interface('identity', 'public')

        log.info("Authenticating against: %s" %
        log.debug("Authenticating project: %s" %

        conn = connection.Connection(
            verify=configobj.getboolean('DEFAULT', 'verify_certs'),

        log.info("Authentication successful")

        return conn

cloud_params is a dictionary with the OS_* vars loaded from the environment
vars, configobj is a configparser object.
