The system validates password character content using the same rules that validate database object names.
For details about object naming, see Teradata Vantage™ - SQL Fundamentals, B035-1141.
Optionally, you can set the DBS Control NameValidationRule field to impose additional object name character restrictions. These restrictions also apply to passwords. Changing the NameValidationRule field does not affect existing passwords. The change only affects passwords that are subsequently created or changed.
For information about setting the DBS Control NameValidationRule field, see Teradata Vantage™ - Database Utilities, B035-1102.
