ccna 200-301 vs ccna 200-125.Cisco Security ACS can be configured to forward user authentication to one or more external user databases. Support for external user databases means that Cisco Security ACS does not need to create duplicate user entries in the Cisco Security user database. In organizations where a large number of user databases already exist (such as Active Directory environments), Cisco Security ACS can leverage the work already invested in building the database without any additional input.For most database configurations other than Windows databases, Cisco Security ACS supports only one instance of username and password. If you configure Cisco Security ACS to use multiple user databases and each database holds a common user name, perform the database configuration carefully. The first database that matches a user's credentials is the only database that Cisco Security ACS uses for that user. For this reason, it is recommended that only one instance of a user name exist in all external databases.To establish an external user database connection, you must access the External User Database page.When configuring the ACS external database, there are 3 main configuration options.UnknownUser Policy - Configure the authentication process for users that are not located in the Cisco Secure ACS database.Database GroupMapping -------------- configures what group permissions external database users inherit when they are authenticated through in Cisco Security ACS. In most cases, when a user is authenticated by an external user database, the actual permissions will be drawn from Cisco Security ACS rather than from the external database.The Database Configuration ----------- defines the externalServer. The Database Configuration screen is used to define the parameters for the external database, with options including.The RSASecurlD token server; The RAD1US token server.External ODBC databases.
