Method of authentication user using server and image forming apparatus using the method

摘要

A method of authenticating a user using a server and an image forming apparatus using the same, the method including: transmitting, from an image forming apparatus to a first server that functions as an authentication server, user authentication information; determining if the first server authenticates the user based on the user authentication information; and transmitting, to a second server that processes image data, the user authentication information if the first server authenticates the user, wherein the second server authenticates the user based on the transmitted user authentication information authenticated by the first server. Thus, the user of the image forming apparatus can be automatically authenticated by the second server by authenticating the user on the first server.

1. A method of authenticating a user of an image forming apparatus using a first server to authenticate the user and a second server to process image data of the image forming apparatus, the method comprising:
transmitting, from the image forming apparatus to the first server, user authentication information; determining if the first server authenticates the user based on the user authentication information; and transmitting, to the second server, the user authentication information if the first server authenticates the user based on the user authentication information, wherein the image forming apparatus transmits an additional information request signal to the first server if the second server requires additional information for authentication, and transmits the additional information to the second server, wherein the second server processes the image data of the image forming apparatus if the second server authenticates the user based on the transmitted user authentication information and the additional information.
