OS10(config)# system-user linuxadmin disable To re-enable or unlock the linuxadmin user, use the no system-user linuxadmin disable command in CONFIGURATION mode. OS10(config)# no system-user linuxadmin disable AAA authentication An OS10 switch uses a list of authentication methods to define the types of authentication and the sequence in which they apply. By default, OS10 uses only the local authentication method. The authentication methods in the method list execute in the order you configure them. Re-enter the methods to change the order. The local authentication method remains enabled even if you remove all configured methods in the list using the no aaa authentication login {console | default} command. NOTE: If you configure multiple authentication methods on Dell EMC PowerEdge MX7000 Ethernet modules - MX9116n Fabric Switching Engine and MX5108n Ethernet Switch - operating in SmartFabric mode, you must configure local authentication as the first method in the list. • Configure the AAA authentication method in CONFIGURATION mode. aaa authentication login {console | default} {local | group radius | group tacacs+} • console - Configure authentication methods for console logins. • default - Configure authentication methods for non-console such as SSH and Telnet logins. • local - Use the local username, password, and role entries configured with the username password role command. • group radius - Configure RADIUS servers using the radius-server host command. • group tacacs+ - Configure TACACS+ servers using the tacacs-server host command. Configure user role on server If a console user logs in with RADIUS or TACACS+ authentication, the role you configured for the user on the RADIUS or TACACS+ server applies. User authentication fails if no role is configured on the authentication server. Also, you must configure the user role on the RADIUS or TACACS+ server using the vendor-specific attribute (VSA) or the authentication fails. Dell EMC's vendor ID is 674. Create a VSA with Name = Dell-group-name, OID = 2, Type = string. Valid values for Dell-group-name are sysadmin, secadmin, netadmin, and netoperator. Use the VSA Dell-group-name values when you create users on a Radius or TACACS+ server. For detailed information about how to configure vendor-specific attributes on a RADIUS or TACACS+ server, see the respective RADIUS or TACACS+ server documentation.
