[MaximeL]

Hi,

In Openstack newton version deployed with sm-lite and R4.1.1.0-12 packages, and with ssl configuration applied to identity, random failures happened when listing projects/users/domains happen under Horizon dashboard.

This bug seems to be existing in several deployment project and known as an Openstack/Kolla bug within apache2 wsgi horizon configuration : https://bugs.launchpad.net/horizon/+bug/1708655

Applying this https://review.openstack.org/#/c/491810/ fixed the SSL hanshakes problems.
