Do you have any support case reference or link to it? I would be interessted if there is any further information available.
Our OpenStack is set up on Ubuntu 16.04 LTS, NetApp OCI is running on Red Hat 7.4 and Red Hat 7.5 hosts.
We configured the controller node, the requested OpenStack admin user and related KVM user with sudo rights on the OpenStack nodes.
I can see the login attempts on the Compute node, as well as the "Test" section when configuring the OpenStack Controller data source completes successfully.
In the logs I see the related error messages:
