ODBC Database
From the System DSN list, select the DSN that is configured on the
Step 6
Cisco Secure ACS server to communicate with the ODBC-compliant relational
database you want to use.
Note
In the DSN Username box, type the username required to perform transactions
Step 7
with your ODBC database.
In the DSN Password box, type the password required to perform transactions
Step 8
with your ODBC database.
Step 9 In the DSN Connection Retries box, type the number of times Cisco Secure ACS
should try to connect to the ODBC database before timing out. The default is 3.
Note
To change the ODBC worker thread count, in the ODBC Worker Threads box,
Step 10
type the number of ODBC worker threads. The maximum thread count is 10. The
default is 1.

If you have not configured on the Cisco Secure ACS server a DSN for the
relational database, do so before completing these steps. For more
information about creating a DSN for Cisco Secure ACS ODBC
authentication, see Configuring a System Data Source Name for an
ODBC External User Database, page
If you have connection problems when Windows starts, increase this
value.
Increase the ODBC worker thread count only if the ODBC driver you are
using is certified thread safe. For example, the Microsoft Access ODBC
driver is not thread safe and can cause Cisco Secure ACS to become
unstable if multiple threads are used. Where possible, Cisco Secure ACS
queries the driver to find out if it is thread safe. The thread count to use is
a factor of how long the DSN takes to execute the procedure and the rate
at which authentications are required.
