You have an Ezmejal Container Platform solution that manages an internally created Kubernetes cluster. The cluster uses AD for Its authentication settings, and users can successfully log into the platform with their domain credentials.
You have created a Tenant on the cluster which has the "AI/ML project" setting enabled on it. You have also created a Notebook cluster within that project. However, users receive an error when they try to log into the Notebook endpoint (Jupyter Hub) with their domain credentials.
What should you check?
A. That the users have a manually created external account that assigns them to the Cluster Admin role in the cluster
B. That the Notebook cluster has a "cluster" connection to the AD server hostname
C. That the users have a manually created external account that assigns them to the Admin status in the AI/ML Project
D. That the Notebook cluster has a "secret" connection with this value: "hpecp-ext-auth- secret"
