Starting with ODBC Driver for Teradata 17.00, passwords cannot be saved when a user creates a new DSN in the ODBC Data Source Administrator. The user can still test the connection by clicking Test after providing a Name or IP Address, Username, and Password. If the user clicks OK to save the DSN, the warning dialog box that prompts the user whether or not to save the password no longer appears, and all information entered except the password is saved in the registry.
For an existing DSN that already had the password saved in the registry, ODBC Driver for Teradata ignores the password value. To delete the saved password for an existing DSN, a user must change the existing DSN by modifying the Data Source Name and save it (thus creating a new DSN based on the old one).
