Information processor, method for managing the same and computer program product
First Claim
1. An image processing apparatus capable of connecting, via a communication line, to an authentication server that memorizes first user account information and performs user authentication based on the memorized first user account information, the image processing apparatus comprising:
- a user information memorizing portion for memorizing access privilege information indicating authorization to use a function of the image processing apparatus for each user who has ever used the image processing apparatus;
a user information deleting portion for automatically deleting at least one of the memorized access privilege information when the user information memorizing portion memorizes the access privilege information in excess of a predetermined value;
an authentication request portion for requesting the authentication server to authenticate a user who desires to use the image processing apparatus;
an access privilege information generating portion, when access privilege information of the user who is authenticated by the authentication server is not memorized in the user information memorizing portion, for automatically generating the access privilege information of the authenticated user to let the user information memorizing portion memorize the generated access privilege information; and
a job control portion determining whether the function specified by the authenticated user is permitted or not based on the access privilege information corresponding to the authenticated user.

Abstract
An information processor is provided that can maintain security in the entire network and use recording media resources efficiently. An image forming apparatus includes a user information memorizing portion for memorizing local user data of users who have ever used the image forming apparatus, a user information deleting portion for deleting any one or more of the local user data when the local user data memorized in the user information memorizing portion has an amount greater than a predetermined value, an authentication request portion for requesting an authentication server to authenticate a user who desires to use the image forming apparatus, and a user information generating portion, when local user data of the user authenticated by the authentication server are not memorized in the user information memorizing portion, for generating local user data of the user in the user information memorizing portion to let the same memorize the generated data.

8. A method for managing an image processing apparatus capable of connecting, via a communication line, to an authentication server that memorizes first user account information and performs user authentication based on the memorized first user account information, the method comprising:
-
letting a user information memorizing portion memorize access privilege information indicating authorization to use a function of the image processing apparatus for each user who has ever used the image processing apparatus; and letting the image processing apparatus perform a first process, a second process, a third process and a fourth process when a user desires to use the image processing apparatus, the first process being a process of requesting the authentication server to authenticate the user, the second process being a process of automatically generating, when the authentication server verifies that the user is an authorized user and the access privilege information of the user is not memorized in the user information memorizing portion, access privilege information of the authenticated user to let the user information memorizing portion memorize the generated access privilege information, the third process being a process of automatically deleting at least one memorized user information other than the generated access privilege information of the user from the user information memorizing portion when the user information memorizing portion memorizes the access privilege information in excess of a predetermined value, and the fourth process being a process of determining whether the function specified by the authenticated user is permitted or not based on the access privilege information corresponding to the authenticated user. - View Dependent Claims (9, 10, 11, 12, 13, 14, 18, 19)

15. A non-transitory computer readable storage medium storing a computer program used for an image processing apparatus that includes a user information memorizing portion for memorizing access privilege information indicating authorization to use a function of the image processing apparatus for each user, the program making the image processing apparatus perform processing of:
-
when a user desires to use the image processing apparatus, requesting an authentication server, which is connected via a communication line to the image processing apparatus and memorizes first user account information, to authenticate the user based on the memorized first user account information; automatically generating, when the authentication server verifies that the user is an authorized user and the access privilege information of the user is not memorized in the user information memorizing portion, access privilege information of the authenticated user to let the user information memorizing portion memorize the generated access privilege information; automatically deleting at least one memorized user information other than the generated access privilege information of the user from the user information memorizing portion when the user information memorizing portion memorizes the access privilege information in excess of a predetermined value; and determining whether the function specified by the authenticated user is permitted or not based on the access privilege information corresponding to the authenticated user.
