Mainframe clients do not support network security features, such as encryption or directory management of users. Unless you make modifications to the Teradata Director Program (TDP), logons from mainframe clients can use only the .logon command, and are similar to the logon shown in Example: TD2 Logon.
For information on how to use TDP functions to alter logon security requirements in a mainframe environment, see Teradata® Director Program Reference, B035-2416.
