RDBMS Synchronization
Custom RADIUS Vendors and VSAs
RDBMS Synchronization enables you to configure custom RADIUS vendors and
VSAs. In addition to supporting a set of predefined RADIUS vendors and
vendor-specific attributes (VSAs), Cisco Secure ACS supports RADIUS vendors
and VSAs that you define. Vendors you add must be IETF-compliant; therefore,
all VSAs that you add must be sub-attributes of IETF RADIUS attribute
number 26.
You can define up to ten custom RADIUS vendors. Cisco Secure ACS allows
only one instance of any given vendor, as defined by the unique vendor IETF ID
number and by the vendor name.
Note For specific information about all actions that RDBMS Synchronization can
perform, see Appendix F, “RDBMS Synchronization Import Definitions.”
RDBMS Synchronization Components
The RDBMS Synchronization feature comprises two components:
• CSDBSync—A dedicated Windows service that performs automated user
and group account management services for Cisco Secure ACS.
• accountActions Table—The data object that holds information used by
CSDBSync to update the CiscoSecure user database.
About CSDBSync
The CSDBSync service uses an ODBC system data source name (DSN) to access
the accountActions table. See Figure 8-2. This service looks specifically for a
table named “accountActions”. Synchronization events fail if CSDBSync cannot
access the accountActions table.
