ODBC Database
Cisco Secure ACS supports PAP, CHAP, MS-CHAP, and ARAP authentication
using a relational database via the ODBC authenticator feature. As with
Windows NT/2000 database support, Cisco Secure ACS’s ODBC-compliant
relational database support enables you to make use of existing user records held
in an external ODBC-compliant relational database. Configuring
Cisco Secure ACS to authenticate against an ODBC-compliant relational
database does not affect the configuration of the relational database. To manage
your relational database, refer to your relational database documentation.
The Windows ODBC feature enables you to create a data source name (DSN),
which specifies the database and other important parameters necessary for
communicating with the database. Among the parameters you provide are the
username and password required for the ODBC driver to gain access to your
ODBC-compliant relational database.
