IMAGE FORMING SYSTEM HAVING USER AUTHENTICATION FUNCTION, IMAGE FORMING APPARATUS, METHOD OF CONTROLLING IMAGE FORMING SYSTEM, AND STORAGE MEDIUM

摘要

An image forming system capable of preventing a change in the data structure of information other than information included in a command transmitted to an image forming apparatus, for use in performing user authentication. Upon receipt of a request command for requesting user authentication from a PC as an information processing apparatus, an MFP as the image forming apparatus determines based on the request command by which of a first authentication method not using a token and a second authentication method using a token is to be performed. When the authentication is to be performed by the second authentication method, the token is generated based on the request command and is transmitted to the PC. The token attached to a token-attached command received from the PC is read out therefrom, and the authentication is performed based on the token read out.

主权项

1. An image forming system including:
an image forming apparatus that performs user authentication by one of a first authentication method which does not use a token and a second authentication method which uses a token, and an information processing apparatus that requests the user authentication to said image forming apparatus, said image forming apparatus comprising: a determination unit configured to receive a request command requesting the user authentication from said information processing apparatus, and determine, based on the request command, by which of the first authentication method and the second authentication method, the user authentication is to be performed; a generation unit configured to generate a token based on the request command when it is determined that the user authentication is to be performed by the second authentication method; a read-out unit configured to transmit the token to said information processing apparatus, receive a token-attached command to which the token is attached from said information processing apparatus, and read out the token from the token-attached command; and an execution unit configured to perform the user authentication based on the token read out.
