The method you use to install Kerberos keys depends on the type of installation, for example:
You may find it useful to check the status of Kerberos keys on the Teradata Vantage system, to help determine the appropriate installation method, before installing a set of keys. See [Optional] Checking Nodes for Existing Kerberos Keys.
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 passwords for the user accounts you created on the KDCs, for example, because password change is required by site security policy, you must regenerate the keys and re-install them on the nodes.
