15.4.9 Configuring Local Database for Management User
Authentication
You can configure the device to use the Local Users table (local database) to authenticate
management users based on username-password combination. You can configure the
device to use the Local Users table (see ''Configuring Management User Accounts'' on
page 73) upon the following scenarios:

LDAP or RADIUS server is not configured (or broken connection) or always use the
Local Users table and only if the user is not found, to use the server.

Connection with the LDAP or RADIUS server fails due to a timeout. In such a
scenario, the device can deny access or verify the user's credentials (username-
password) locally in the Local Users table.
If user authentication using the Local Users table succeeds, the device grants
management access to the user; otherwise access is denied. The access level assigned to
the user is also determined by the Local Users table.
