The SQL procedure can decide among 1, 2, or 3 to indicate a failure, depending
on how much information you want the failed authentication log files to include.
A return code of 4 or higher results in an authentication error event. These errors
do not increment per-user failed attempt counters. Additionally, error codes are
returned to the AAA client so it can distinguish between errors and failures and,
if configured to do so, fall back to a backup AAA server.
Successful or failed authentications are not logged; general Cisco Secure ACS
logging mechanisms apply. In the event of an error (CSNTresult equal to or less
than 4), the contents of the CSNTerrorString are written to the WindowsNT/2000
Event Log under the Application Log.
Configuring a System Data Source Name for an ODBC External User DatabaseOn the Cisco Secure ACS server, you must create a system DSN for

To create a system DSN for use with an ODBC external user database, follow
these steps:
Step 1 In Windows Control Panel, double-click the ODBC Data Sources icon.
Step 2 In the ODBC Data Source Administrator window, click the System DSN tab.
Step 3 Click Add.
Step 4 Select the driver you need to use with your new DSN, and then click Finish.
