The error you posted suggests you reached keystone, got some answer, but it is not sufficient for SDK to continue. It can be caused by misconfiguration on keystone.

But in any way you should provide logs (add `openstack.enable_logging(debug=True)`) and provide it here. Without this it is not possible to give you any other information.

Does openstacksdk support keystone auth type "v3tokenlessauth"?

I got this error message when trying to enable openstacksdk with
auth_type="v3tokenlessauth"

openstack.exceptions.NotSupported: The identity service for TEST:
exists but does not have any supported versions.

The following are the possible relevant documents I could find, and
there is no place mentioning the support for tokenless auth using
openstacksdk:
https://docs.openstack.org/openstacksdk/latest/user/config/configuration.html
https://docs.openstack.org/keystone/train/admin/configure_tokenless_x509.html
