I have a cdp 7.3.1 instance, and I want to hookup okta authentication to the impala service, so that when tableau connects to the impala, it will trigger authentication / call back with a okta server(I already have admin controls of it, and have scope/application etc). on this instance, I already enabled kerberos, knox and not sure if I need to enable ssl as well, I can't find any documentation for it, can some one walk me through the setup? I mostly rely on chapgpt, and had some issues.

I cloned a cdp 7.3.1-1 one node that is kerb enabled, to connect to a kdc server in a different domain. During the kerberos wizard, I choose "Administration" | "security" | "Kerberos Credentials" | "Import KDC Account Manager Credentials", and put in valid username and password, then I get "kinit: Preauthentication failed while getting initial credentials" the same user name / pwd pair, I can do kinit xx@TEST.LAN, and get valid results from klist. So I know the credential is good. I have validated on the AD server, use delegation wizard to give add, modify delete rights to the user xx. If I run Generate Missing Credentials, I see "SIMPLE_PWD_STR='-x -D cloudera@old kdc server -w REDACTED'", and this refers to the old kdc server. So I need to know how to change the setting on ldaps and how I can solve the issue with kinit: Preauthentication failed while getting initial credentials
