YES! It is quite a battle to keep SSL (native SSL and tls-proxy) working
in devstack given the pace of development of the related projects. I've
got a couple of reviews out now which may bring things to a state where
the tempest smoke suite will pass in SSL mode.

I haven't seen that. What does your local.conf look like? Honestly I
mostly test with the configuration that devstack-gate uses to have any
chance of SSL being part of CI.

Note too that I'm trying hard to be able to stop using service-specific
CA options and instead add all CA certs to the global cert store and
then things will just work. I originally start pushing for per-client
SSL config sections and got pushback from a number of PTLs that didn't
want their config options exploding.

That leads to the python-requests problem. It includes a nifty function,
where(), which returns the location of the global CA bundle. Packagers
set this to match what is on individual platforms (Debian, Ubuntu &
Fedora/RHEL anyway).

Unfortunately devstack often requires newer versions that ships with the
OS's causing pip to install the upstream version, which of course
defaults to using the bundle it ships, which ends up breaking lots of
things. I'm stumped as to how to fix that. I made a ham-handed attempt
at fixing it last year and was appropriately smacked down.
