Public bug reported:

Hi there! i am trying to integrate OpenDaylight Be and OpenStack Liberty
on Ubuntu 14.04.4 Server. Keystone was working fine before integrating.
After installing python-pip and networking_odl (apt-get install python-
pip and pip install networking_odl) keystone throws 505 internal server
error. (No handlers could be found for logger
“keystoneclient.auth.identity.generic.base” ERROR (InternalServerError):
Internal Server Error (HTTP 500)).Installing again from scratch didn't
solve the issue.Keystone log in apace2 log showed the following error.
