First, NAD obtains the username prompt and transmits the username to the server, and then again the server is contacted by NAD to obtain the password prompt and then the password is sent to the server. The HWTACACS client sends an Accounting-Request(Stop) packet to the HWTACACS server. In 1984, a U.S. military research institute designed the earliest TACACS protocol (RFC 927) to automate identity authentication in MILNET, allowing a user who has logged in to a host to connect to another host on the same network without being re-authenticated. Before we get into the specifics of RADIUS and TACACS+, let's define the different parts of AAA solutions. > Similarities The process is started by Network Access Device (NAD client of TACACS+ or RADIUS).
