<P>PROBLEM TO BE SOLVED: To solve the problem in which, in a conventional technique for setting a single sign-on (SSO), if SSO mapping can be set erroneously between IDs included in tenants of different companies in setting the SSO mapping, a user authenticated as an ID of a certain tenant of a certain service is authenticated as an ID of a different tenant when accessing another service with the SSO, and the user can access information of a different company. <P>SOLUTION: An information processing system allows a user to be authenticated in both systems for setting SSO mapping, and to obtain both ID lists under an authority of the authenticated ID, and to perform SSO setting only between IDs included in the obtained ID lists. <P>COPYRIGHT: (C)2013,JPO&INPIT |
