You may find it useful to check the status of Kerberos keys on the Teradata Vantage system and Unity server (if used), to help determine the appropriate installation method, before installing a set of keys. See Checking Nodes and Unity Servers for Existing Kerberos Keys (Optional).

If Vantage users can be authenticated in more than one domain, you must install a set of keytab files for a KDC in each domain. If your site requires the installation of multiple keytab files, verify that each file has a unique keytab file name.

If you change the database node or Unity server passwords for the user accounts you created on the KDC(s), for example, because password change is required by site security policy, you must regenerate the keys and re-install them on the nodes.
