Change password screen shown on page refresh for autologin user
If an unauthenticated/autologin user accesses a public workspace dashboard on an Incognito tab and then refreshes or tries to reload the page, it can unexpectedly trigger the display of the Change Password modal.
Workaround:
To resolve this issue, change the autologin user's password once using the Change Password modal. After changing the password, the issue should no longer occur and the autologin functionality will work as expected.

When using SAML, users get removed from “Default group membership for new users” after second login

Users are removed from the “Default group membership for new users” (viz_guest_group by default) after they log in for the second time. In Cloudera Data Warehouse, non-admin users receive “Database Admin” roles based on their membership in a local “viz_guest_group” default user group. This means that they will lose their role-based privileges after logging in twice.

Workaround:

An admin user should manually assign the “Database Admin” role to a SAML-synced group.

Data compatibility check does not work for SQL-based datasets that join on multiple tables

When importing in visual artifacts that use SQL-based datasets, the “data compatibility” check may fail with an “IndexError: list index out of range” error, if the dataset joins multiple tables.
