Comment 1 for bug 1715091

Hi! We'd better ask Renat, but as far as I understand, we should not use native keystone authentication module in mistral client[1]. It's outdated and doesn't support many keystone features.

The recommended OpenStack way is to use python-openstackclient and osc-lib for authentication against keystone. It supports ssl and is developed by the community!
Mistral client provides a plugin for osc, which should be used for communication with Keystone[2].
