Title:
authentication code hangs when there are three or more admin keystone
endpoints
Status in OpenStack Identity (keystone):

Status in python-keystoneclient:
Expired
Bug description:
I'm running stable/pike devstack, and I was playing around with what
happens when there are many endpoints in multiple regions, and I
stumbled over a scenario where the keystone authentication code hangs.
My original endpoint list looked like this:
ubuntu@devstack:/opt/stack/devstack$ openstack endpoint list

I was able to successfully run the following python code:
from keystoneauth1 import loading
from keystoneauth1 import loading
from keystoneauth1 import session
from keystoneclient.v3 import client
loader = loading.get_plugin_loader("password")
auth =
loader.load_from_options(username='admin',password='secret',project_name='admin',auth_url='http://128.224.186.226/identity')
sess = session.Session(auth=auth)
keystone = client.Client(session=sess)
keystone.services.list()
I then duplicated all of the endpoints in a new region "region2", and
was able to run the python code. When I duplicated all the endpoints
again in a new region "region3" (for a total of 39 endpoints) the
python code hung at the final line.
Removing all the "region3" endpoints allowed the python code to work
again.
During all of this the command "openstack endpoint list" worked fine.
Further testing seems to indicate that it is the third "admin"
keystone endpoint that is causing the problem. I can add multiple
"public" keystone endpoints, but three or more "admin" keystone
endpoints cause the python code to hang.
