Contributor guide
Research direction
Start with the Kyuubi Web UI sign-in flow and the kyuubi.authentication setting, reproducing the failure on version 1.9.1 with KERBEROS enabled. Collect the missing Kyuubi Server and Engine logs and configuration, then compare the NONE and KERBEROS sign-in paths. Done means Web UI sign-in and sign-out work with KERBEROS authentication.
