CiscoSecure User Database

User Guide for Cisco Secure ACS for Windows Server

The CiscoSecure user database is the database internal to Cisco Secure ACS. It

supports authentication using ASCII, PAP, CHAP, MS-CHAP, ARAP, LEAP,

EAP-MD5, EAP-TLS, and PEAP(EAP-GTC).

The CiscoSecure user database is crucial for the authorization process. Regardless

of whether a user is authenticated by the internal user database or by an external

user database, Cisco Secure ACS authorizes network services for users based

upon group membership and specific user settings found in the CiscoSecure user

database. Thus, all users authenticated by Cisco Secure ACS, even those

authenticated by an external user database, have an account in the CiscoSecure

user database.

The CiscoSecure user database draws information from a number of data sources,

including a memory-mapped, hash-indexed file,

database format), and the Windows Registry.

structure, so searches can occur logarithmically rather than linearly, thus yielding

very fast lookup times. This enables the CiscoSecure user database to authenticate

users quickly.

Unless you have configured Cisco Secure ACS to authenticate users with an

external user database, Cisco Secure ACS uses usernames and passwords in the

CiscoSecure user database during authentication. For more information about

specifying an external user database for authentication of a user, see
