PROBLEM TO BE SOLVED: To solve the problem that, though there is a standard protocol, called OAuth, for creating an added value by making a plurality of services coordinate with each other and OAuth enables an application to access a resource by obtaining explicit authorization of a user, and the cases where one person has a plurality of terminals increase in recent years, the conventional method needs authorization operation individually for each terminal that a user has and thereby reduces convenience.SOLUTION: On the basis of the fact that authorization operation is performed at least once in a terminal associated with a tenant, authorization operation of a user belonging to the tenant is omitted.SELECTED DRAWING: Figure 9 |
