The default value of the MaxLogonAttempts parameter is 0, that is, allow unlimited failed logon attempts.

Enter the number of allowable failed logon attempts into the DBC.SysSecDefaults table MaxLogonAttempts column.

If you enter a negative value, the system accepts the UPDATE, but the value reverts to the default zero value at the next restart, and writes an error message to the event log:

3698: SysSecDefaults table has a negative value in an integer column

If user DBC exceeds the maximum allowable logon attempts, user DBC could be locked out. Then the only way user DBC can log on is through the TSTSQL console. Contact your Teradata support representative for more information about TSTSQL console.
