Apparatus, authentication system, authentication control method, authentication control program, and computer-readable recording medium having authentication control program

摘要

A disclosed image forming apparatus includes an authentication information reception unit configured to receive first authentication information input to the image forming apparatus, an authentication control unit configured to send the first authentication information to a first authentication apparatus connected to the image forming apparatus via a network and cause the first authentication apparatus to carry out a first authentication based on the first authentication information, and an authentication information recording unit configured to record, when the first authentication based on the first authentication information has succeeded, the first authentication information therein as second authentication information. In the image forming apparatus, the authentication control unit carries out, in a case where the first authentication apparatus is not available, a second authentication based on the second authentication information recorded in the authentication information recording unit in lieu of the first authentication based on the first authentication information.

主权项

1. An image forming apparatus comprising:
circuitry configured to:
connect via a network to an authentication apparatus and to at least one other image forming apparatus;register the authentication apparatus and at least one of the at least one connected other image forming apparatus;store user information of an authenticated user of the image forming apparatus;send a first authentication request and an authentication target information to the registered authentication apparatus in response to acquiring the authentication target information;execute user authentication at the image forming apparatus of the authentication target information based on the stored user information of the authenticated user of the image forming apparatus when the authentication apparatus is not available to carry out the user authentication in response to the first authentication request;send a second authentication request and the authentication target information to one of the at least one registered other image forming apparatus when the authentication apparatus is not available to carry out the user authentication in response to the first authentication request and the user authentication at the image forming apparatus of the authentication target information based on the stored user information of the authenticated user of the image forming apparatus has failed, the one of the at least one registered other image forming apparatus storing user information of an authenticated user of the one of the at least one registered other image forming apparatus; andcreate an access history data identifying the image forming apparatus when the image forming apparatus does not authenticate the user at the image forming apparatus, wherein send the second authentication request and the authentication target information to the one of the at least one registered other image forming apparatus includes sending the second authentication request, the authentication target information, and the access history data to the one of the at least one registered other image forming apparatus, and wherein the image forming apparatus and the at least one other image forming apparatus are the same type of image forming apparatus.
