After you generate Kerberos keys on the Linux MIT KDC(s), you must securely move copies of the set of keytab files for database nodes from the KDC to a temporary location on any node of the corresponding database system, and move copies of the set of keytab files for each Unity server (if used) to the corresponding server.
If a database system or Unity server resides in multiple domains, make sure you move the keytab files from the KDC in each domain. Save the copies of the keytab files here: /opt/teradata/tdat/tdgss/site/domain_name.sys_name.keytab.
domain_name.sys_name is defined in Generating the Key for the First Node or for a Unity Server.
This is a temporary location to use when you install the keys to the permanent location in Installing the Kerberos Keys. Make sure that each keytab file has a unique file name.
