All - I made the change to the auth_url that  Anusha suggested.
Same problem as before " Cannot authorize API client"
2016-07-22 14:13:50.835861 ***** calling policies_list =
client.list_policy()*****
2016-07-22 14:13:50.836062 Unable to get policies list: Cannot
authorize API client.

I used the token from the log output to query the Congress API with
the keystone v3 token - no issues.
curl -X GET -H "X-Auth-Token: 18ec54ac811b49aa8265c3d535ba0095" -H
"Cache-Control: no-cache" "http://192.168.56.103:1789/v1/policies"

So I really think the problem is that the python-congressclient
doesn't support identity v3.
I thought it did, but then I came across this:
"support keystone v3 api and session based authentication "
https://bugs.launchpad.net/python-congressclient/+bug/1564361
This is currently assigned to Anusha.
I'd like to start work on it since I am becoming familiar with keystone v3.

Thoughts?

aimee
