Abstract:
1. An image forming apparatus, comprising: a first determination unit that determines whether or not server setting information has been received when the image forming apparatus is activated by an activation instruction, wherein the server setting information is required to activate the image forming apparatus; a second determination unit that determines whether an authentication method of the image forming apparatus at the last activation is a device authentication or an application authentication, without displaying an authentication screen for requesting input of user information, when it is determined by the first determination unit that the server setting information has not been received, wherein the device authentication allows a user to use all functions of the image forming apparatus in response to successful authentication of the user and the application authentication allows a user to use a partial function of the image forming apparatus in response to successful authentication of the user; and a control unit that displays all functions of the image forming apparatus being disabled until reception of the server setting information if the authentication method at the last activation is determined to be the device authentication, and controls the image forming apparatus to disable a partial function which communicates with the server but to enable a remaining function if the authentication method at the last activation is determined to be the application authentication.
