  • Verify that the KRB5 mechanism is enabled on all clients that use Kerberos authentication and on all Teradata Vantage systems to which they connect.
  • The client from which the user logs on must be running Windows, Linux, or supported TTU UNIX clients (except IBM z/OS clients) and the system must be setup as shown in Working with Kerberos Authentication.
  • Set the Kerberos authentication mechanism to be used (KRB5 or SPNEGO) as the client default, or the user must specify it at logon.
  • The Vantage and Kerberos clients must be set up as shown in Working with Kerberos Authentication.
  • DBS Control and Gateway Control must be set to allow external authentication. See About External Authentication Controls.
  • All users authenticated by Kerberos must have LOGON ... WITH NULL PASSWORD privileges defined in each Teradata Vantage system to which they can log on. See Working with User Privileges in Teradata Vantage.
  • The domain username used at initial logon to the network must match a Teradata Vantage username. For acceptable logon username forms, see Logging on Using Single Sign-on with Kerberos.
