By default, monitoring points support a single Web Admin user that is authenticated using a locally stored password. For some monitoring points, TACACS+ can be used to perform authentication. Once TACACS+ is enabled, any user configured on the TACACS+ server (including one having the username root) can log in via Web Admin. The local monitoring point username is not authenticated locally as long as TACACS+ is enabled.
