Actually, you should not be able to simply cycle through a set number of passwords and back to the original password all in the same day. You cannot reuse a password for a number of days as determined by the parameter Password Reuse in the DBC.SysSecDefaults table.
The following is taken from the Security Administration manual:
The security administrator sets up the password features for a Teradata RDBMS by updating columns of a single row in user DBC table DBC.SysSecDefaults. The single row in the table is read by the Teradata RDBMS at system startup. The software uses the values in the columns to determine whether the option has been selected. Note: The system must be restarted to read the DBC.SysSecDefaults table and to make changed values operational. The rules selected apply to all users attempting to log on to the Teradata RDBMS, regardless of the logical client system from which the logon is received. The only override to the rules is the null password option, which allows a user to log on without a password and bypass all rules pertaining to user authentication. Password Expiration Allows the security administrator to define a time span during which a password is valid. After the time elapses, the user must change the password.
