Which authentication method should an administrator run as a command in the NetBackup Appliance Shell Menu (CLISH), under Settings > Security >…

The Veritas NetBackup Appliance utilizes the Kerberos protocol as the underlying framework to authenticate users from Network Information Service (NIS) domains. To enable appliance access for NIS users, an administrator must first configure the Kerberos settings through the CLISH. This involves running the Kerberos command under the Settings > Security > Authentication path to define the Kerberos realm, Key Distribution Center (KDC), and other necessary parameters. This configuration establishes the secure communication channel required for the appliance to validate NIS user credentials against the central authentication server.

A. LDAP: This command is used to configure authentication specifically against a Lightweight Directory Access Protocol (LDAP) server, which is a different directory service from NIS.

B. ActiveDirectory: This command is designated for integrating with Microsoft Active Directory. While AD uses Kerberos, this option is not used for a generic NIS environment.

D. LocalUser: This command is for creating and managing user accounts that are stored directly on the NetBackup appliance itself, not for integrating with external directory services.

Section: Chapter: "Managing users on the appliance

" Sub-section: "About NIS and LDAP user authentication."

Content: The guide explicitly states

"To configure NIS or LDAP users

you must first configure Kerberos authentication on the appliance. The appliance uses Kerberos authentication to let you log in to the appliance as an NIS or LDAP user." This directly links NIS user configuration to the Kerberos command.

and Server

which are essential prerequisites for enabling authentication for users from NIS or LDAP domains. The guide shows this is the command to be run for the initial setup.
