Error when enabling keystone V3

[Ryu Ishimoto]

Error seen in the Red Hat dashboard after enabling keystone v3 in horizon:
it appears that Horizon is making a call: get_version_from_service(service)
and it's trying to parse the endpoints of the service, and at least for the midonet service the array of endpoints is empty
and that throws an error: IndexError: list index out of range

Toni's comment:

We'd need the configuration of Keystone, Neutron, Midonet and how the midonet service should be registered with keystone in order to reproduce this bug.

Original JIRA: https://midonet.atlassian.net/browse/MNP-168

[Ryu Ishimoto (ryu-midokura)]

Will track this as a blueprint:

as it seems ryu confirmed, let's reflect it to status.

[YAMAMOTO Takashi (yamamoto)]

the information asked has never provided. i guess it was a deployment issue.
keystone v3 is working these days as far as i know.
