No special setup is required if you use the default Teradata authentication.
Additional setup of TDGSS configuration files may be required on Analytics Database nodes, depending on the features you implement.
TDGSS Channel Binding
TDGSS channel binding enables binding TDGSS authentication mechanisms to secure channels at lower network layers for those mechanisms that support channel binding, such as the PROXY mechanism. Channel binding verifies the endpoints of the lower level network layers to eliminate man-in-the-middle attacks. In the case of the PROXY mechanism, channel binding also makes it more difficult to use stolen certificates to pretend to be a legitimate endpoint. Use Gateway Control to enable channel binding:
gtwcontrol -j yes
