If you install Kerberos in a location other than the standard /usr/lib64, you must also update the TdgssUserConFigFile.xml for database, and the TdgssUnityConfig.xml for Unity servers (if used), as shown in the procedure that follows, after you install Kerberos to the alternate location. This procedure is required on each Teradata Vantage system, and on each Unity server (if used), so the configuration file can access the Kerberos library libgssapi_krb5.so.
Teradata recommends that you complete all Kerberos setup tasks required on the Teradata Vantage nodes and on the Unity server, if used, before you do any other edits to KRB5 mechanism properties.
