PROBLEM TO BE SOLVED: To solve the problems that the conventional single sign-on setting method is not satisfactory because a user of a tenant having a different SP can be subjected to SSO mapping to an IDP in the case where a plurality of tenants use the same SP, that the opposite situation is not satisfactory in the same manner, and that SSP mapping has to be performed to a registered IDP by a proper method because an SSO mapping method for guaranteeing security is different due to IDP characteristic.SOLUTION: A proper SSO mapping function is provided to each of a plurality of IDPs. Therefore, a mapping function is preliminarily associated with each IDP, a mapping function corresponding to an IDP selected from available IDPs by a user is executed, and mapping information is registered. |
