12: User Authentication This chapter describes authentication methods for users who attempt to log into the SLC console manager by Telnet, SSH, the console port, or one of the device ports. It includes descriptions of user rights, NIS, LDAP, RADIUS, Kerberos, and TACACS+ options. The chapter contains the following sections:  Overview of Authentication  User Rights  Authentication Methods  Local and Remote Users  Local/Remote User Settings  NIS  LDAP  RADIUS  Kerberos  TACACS+  SSH Keys  Custom User Menus Note: The features and functionality described in this chapter specific to PC Card use are supported on SLC -02 part numbers. The features and functionality specific to USB port use are supported on SLC -03 part numbers. Overview of Authentication The User Authentication tab enables you to assign the order in which the SLC console manager uses the authentication methods. The local/remote user authentication is the default and the first method the SLC device uses to authenticate users. You can disable local/remote user authentication or assign it a lower precedence. Note: Regardless of whether local/remote user authentication is enabled, the local/ remote user sysadmin account is always available for login. Authentication occurs in the order of precedence until a successful authentication is obtained or by using the first authentication method that responds. If the server is down, the first responding authentication is used. If you have the same username defined in multiple authentication methods, the result is unknown. For example, there is an LDAP user named "joe" and an NIS user named "joe" so the order of authentication is: 1. Local Users 2. LDAP 3. NIS SLC™ Console Manager User Guide 139
