Public bug reported:
If you have a neutron.conf containing a nova section that makes use of
the `auth_section` configuration option to point the keystone loader at
credentials in a different section instead of repeating it the tool will
crash.
The neutron-server is just fine with loading the same configuration. I
suspect there is some initialization missing in the tool to allow it to
parse this correctly.
The fix provided for bug 1882020 did address this at the time, but since
then it has returned.
Looking at the traceback I suspect the adding of segments support made it
appear again:
